Slackware :: Submit An Enhancement Request - Envar PATH When Run By Udev
Apr 7, 2010
The value of envar PATH for processes run by the udev system is "/usr/gnu/bin:/usr/local/bin:/bin:/usr/bin:.". If peer review (that's you!) agrees it is a poor choice how can I submit an enhancement request? The man pages do not say anything about bug reporting. Here are reasons why it is a bizarre choice:There is no /gnu/bin directory on as-installed Slackware. /usr/local/bin is empty (or very nearly empty?) on as-installed Slackware. Processes running under udev run as root; having "." in PATH is not good practice when running as root. Processes running under udev are likely to be doing "system" work so executables from the sbin directories are likely to be used. For example, udevadm itself is /sbin/udevadm. Presumably this PATH is set by udevd itself; it is not the PATH in effect when udevd is started by rc.M. AFAIK udevd's PATH is not configurable. The workaround is for processes initiated by udev to set a sane PATH for themselves, perhaps "/usr/sbin:/sbin:/usr/bin:/bin". EDIT: seen on Slackware 13.0 32 bit. EDIT2: rc.udev is run from rc.S, not rc.M as stated above

I've recently updated my Slackware 13.1 system to the Slackware current. Although I have created my "initrd" image without specifying the "-u" option to "mkinitrd" it still starts up "udev".
That is causing me some difficulty because I am using "dmraid" to detect my RAID arrays. I had created my own device names such as "/dev/sdr2" for my root partition. With 13.1 I had no problem, since "udev" was not started by the "initrd" unless the "-u" option was provided. The current version seems to start up "udev" even without that option.
Is there a way to disable "udev" in the "initrd", or is there a way to specify custom "udev" rules for an "initrd"? I tried placing a "10-local.rules" file in the "etc/udev/rules.d" directory of the "initrd-tree" but that file had no effect on the device names generated by "udev" during the "initrd".
Here is my script that creates the "initrd".
Code:
ROOTDEVNAME="/dev/sdr2"# Name of root device
LINUXVER="2.6.35.7-smp"# Linux modules version
CLIBVER="2.12.1"# C library version
ROOTDIR="/boot/initrd-tree"# Location of root filesystm
[code]....
It will be helpful for me to understand "udev" issues related to an "initrd" because I will eventually try to use "mdadm" instead of "dmraid". So far I have only been able to get my system to boot from the RAID array using "dmraid" and I often run into new problems when I update Linux. Still, Slackware has proven to have the best support for booting from my RAID array because of the user community, documentation and flexibility.

Are there any prerequisites which much be met in order for udev to create /dev/usb/hiddev* nodes?
I have two Slack 13.0 systems, each connected to a APC UPS via USB, one of which creates a hiddev0 node and the other doesn't. apcupsd can't find the UPS unless this node is present.
The "working" system has been stable in its current configuration for so long that I honestly can't remember if I had to tweak anything in this regard. I've verified that it doesn't use any local udev rules to create this node, and to the best of my knowledge there are no external scripts or processes which would create it either.
The non-working system has a similar configuration - no local rules and/or scripts which touch usb devices or nodes.

I have noticed that PV and team are currently very receptive to proposed changes and additions for the upcoming Slackware 13.37 so I thought I would add my own request as well .On reinstallation or upgrade the stock slrn slackbuild overwrites the vital configuration file for slrnpull: slrnpull.conf. This file contains not only the newsgroups requested for reading but also the numbers to be downloaded as well as the time the posts will remain in the spool

I'm trying to configure gpsd 2.96 to start automatically from udev rule on a Slack 13.37 box.1. I've compiled and installed gpsd from sources and made sure it starts manually.2. I've copied the /lib/udev/gpsd.hotplug and /lib/udev/gpsd.hotplug.wrapper scripts in their places from the source tree and made them executable.3. I've copied the gpsd.rules file from sources into /etc/udev/rules.d4. I renamed it 99-persistent-gpsd.rules to run late in the bootup process.5. I've copied the /etc/default/gpsd file from sources and made sure it has the right settings inside.
Now, for the results. If I plug the gps usb dongle in while the system runs, it starts gpsd if it is not started, and it connects to it just as it should. But if I start the system with the dongle in, gpsd doesn't get started during boot. I can't find any relevant message in /var/log/syslog or /var/log/messages for boot time. There is stuff there from when I plug the dongle in while the system is running though. It's like udev ignores the rules for it at boot time.Is there something in the Slackware boot scripts that would prevent running those scriptssd.hotplug.wrapper which in turn runs /lib/udev/gpsd.hotplug which is a Python script)?Here is the contents of 99-persistent-gpsd.rules (ignore the comments referring to Debian, it was meant for a Debian box). My usb gps adapter is the first one - the Prolific chipset one:
Code:
# udev rules for gpsd
# $Id: gpsd.rules 5861 2009-08-03 13:41:01Z bzed $

I have just installed slack-13.1 on an acer aspire one netbook from a usb stick by booting the install kernel with noudev. I was able to do a complete install including lilo but upon rebooting my boot hangs when encountering my webcam.I see enough info to note the id as 0c45:62c0. This is a microdia webcam which I may be able to do something about later but in the first instance I'd like to be able to boot my system. The bios is very basic and there is no way to disable devices.

I just bought a USB hard disk and when I plug it in it gets mounted as owner root and group root. I tried writing a udev rule for it based on the following guide:Nothing seems to work, it always mounts as root. Slackware 13.1, KDE, Dell Optiplex GX280, Western Digital Passport USB 320 gig drive.I am a member of the plugdev group, so it seems to me a rule should not even be necessary.

Some times I boot up, and udev has labelled what is usually eth0 as eth1. Of course, my rc.inet1.conf is configured for seeing internet at eth0, so no connection, quite obviously. Then I reboot and the device label is back to "eth0". Actually I'm still not able to get connected, even at eth0, despite my nameservers being OK, and the default route gateway being all OK. PS. I have a static ip address.

Noticed this on boot up the other day, but it doesn't seem to have a negative effect. Everything appears to be running just fine.
"Triggering udev events: /sbin/udevadm trigger --type=failed"
Is this something that needs to be resolved or ignored?

I switched today to slackware-current on one of my desktops to play with it and ran directly into a problem.
Since ages my lilo.conf has two entries for slackware. One for runlevel 3 and one for runlevel 4.
Code:
Since the upgrade this is no more possible because I get a kernel panic as soon as udevadm trigger is called. The stack says something about an unknown boot option. Because that i removed the append lines from my lilo.conf and i was able to boot the system. The crash happens when udev is called from within the ramdisk and afterwards. I tried both.
My question is now. Is this a bug in udev or expected? I have this setup since at least 5 years and had never problems with that. What do I have to do to be able to select the runlevel at boot time?

I am working on getting my software packages installed on my fresh Slackware64-13.0 installation. Some (but definitely not all) of my executables are unable to be run.
I understand what PATH is for. It is for locating files, folders, executables in those directories when running from a Terminal window.
So, for example, I have just installed Cisco VPN Client for Linux, and it is the strangest thing. I should have access to this. I must not be understanding something here. Does anyone have any idea why this is not working for me? I have put in an example of what I am talking about.
I have no idea why this is not working.

I have searched the web and these forums and have come up empty-handed. There must be a way... even and easy way... to submit or edit freedb information for a CD. Grip supposedly had the ability but 1) it seems to be no longer maintained and 2) it seems it requires sendmail to be installed. I've read that submissions can be made by email, but 1) I've found no information on how to do this (ie structure and content of email) and 2) that's a lame way to have to do this.
This shouldn't be difficult (much less impossible). What am I missing?

I have created a simple web form which pokes a PHP script:
<form name="update" action="http://www.mysite.com/script.php" method="POST">
<input name="submit" type="submit" value="submit">
</form>
I can easily surf along to the URL [URL] and click the submit button which pokes script.php and everyone's happy. Automating this in iMacros or Selenium - no problem.
I want to automate this in a bash cron on the same server - preferably as a one-liner.
I *thought* something like this might work:
Code:
wget --spider --post-data="submit=submit" http://www.mysite.com/wget.html
or
Code:
curl -d "submit=submit" http://www.mysite.com/wget.html
and many variations thereof but no luck.
Is there ANY way I can click the submit button from a Bash command line? Curl, wget, lynx - one of these simply MUST be capable of this.
I do not want to run script.php from the command line - there are loads of relative links etc.

The problem with ssh is that it's a live connection; rubbish over a slow or packet loss full connection like satelite. Surely there's got to be something out there that allows you to compose the command you want and then submit it in one go with the return key?

I use this command:
Code:
find ./ -atime +360
to figure out the files that haven't been accessed since 360 days. The command above will return results like this:
Code:
/uploads/2010/02/some-file-name.ext
/uploads/2009/08/another-file-name.ext
... etc
I'm taking here about tins of directories, thousands of files. I'm looking to find a command that makes me able to move the results above to another path, and to create that path once it doesn't exist like below:
Code:
mv /uploads/2010/02/some-file-name.ext /old-files/uploads/2010/02/some-file-name.ext
But I want the executed command to create this path
Code:
/old-files/uploads/2010/02/
If it doesn't exist.
