I've just upgraded to Fedora 15 and have been fiddling with the new systemd which replaces sysvinit. I googled quite a bit, but was really unable to find any real information about how it works and why it's better.
View 1 RepliesI am working on a light version of linux for no particular reason other than to see how small I could make it. I was wondering if INIT was necessary, or if I could perform all of the INIT-related tasks (fsck, unmounting, etc) by hand/bash scripts?
I do not need multi-user functionality (Or much of anything for that matter). I started off with a Gentoo base 2.0.2 Install with kernel 2.6.38.
My previously running debian system recently started failing with systemd failure messages as some services are being started. It never completes. I can log into recovery mode.
I added systemd.log_target=kmsg systemd.log_level=debug into my grub parameters.
After I do that all that I see scrolling down the page on boot are:
systemd-journald[36] /dev/kmsg buffer overrun, some messages lost
and the occasional
systemd[1] Looping too fast Throttling execution a little
Is there a way that I can boot without systemd using sysvinit?
I would like to learn how to program on Linux but I cant find any informaton on GCC. The manual is like a list that has no meaning to a novice. Are there any books out there that are not writen by Stallman? Is it more practical to learn it on another O.S and then transpose the information over to the Linux context?

So far I have no idea how to read the information data or payload of the UDP package in order to read the content of the traffic for example if there is any PTR, A, MX, etc Resource Record.According to the RFC 1053 there is a header that is possible to use in order to easily get this info.
View 5 Replies View RelatedIm am building a Linux distro. It will be very tiny and fast.
I only have a minimal linuxkernel (bzImage) who is 1,2 mb big. And then I have Busybox who is 174,6 kb big.
The commands in busybox is: cd, ls, mkdir, rmdir, wget, httpd, clear, rm, poweroff, halt, reboot, fdisk, mount, umount, free, and cp.
When I compiled the kernel i use initramfs/initrd function and point it to a folder where initrd/initramfs source is.
The kernel works OK with others initramfs/initrd files. But not with my own.

Here is how the end of the kernelcomplie look like.

Here is my init file who is the initrd/initramfs source.
Quote:
The initramfs folder contains "bin" (folder) and "init" a file. No more.
The problem is that the kernel cannot find/read init file.
I have a debian system that's freezing in the boot sequence at "Setting system clock".Several sites I looked at recommended changing the init scripts to disallow hardware access to the clock. But, I can't boot! Is there a parameter I can pass to the kernel at boot so that it will skip init scripts?

View 3 Replies View RelatedI upgraded to Fedora 15 using preupgrade after I failed to upgrade or install it clean through DVD. But, after the preupgrade process finished, I can't boot my system even into init mode 3. I am able to boot into the init mode 1 and can see that many of the packages have been upgraded to fc15. I tried to start the x server from init mode 1. My nVidia screen even popped up. But after that the screen went totally blanked.

View 4 Replies View RelatedAfter a kernel update action, it seems that I'm unable to boot a system anymore. First off, after installing the kernel, and trying to shutdown to boot to the new kernel, the system replied with INIT: no more processes left in this runlevel. Kernel update was performed from to the following versions 2.6.18-128.el5.img -> 2.6.18-164.11.1.el5.img . The system is a VMWare virtual machine. When trying to reboot, the system passes GRUB, starts initializing and after loading the dm it stops for a few seconds at the message Waiting for new devices, show the following message:
Setting up new root fs no fstab.sys, mounting internal defaults. After this and a few other messages, it displays : INIT: version 2.85 booting INIT - No more processes left in this runlevel INIT: Id "x" respawning too fast : disabled for 5 minutes And then it just hangs. This is the output of my inittab:
[code]...
The system boots into failsafe, but still shows the errors mentioned.
I am running Centos 5.5 with all the GUI stuff, including nx server and webmin.Sometimes while watching the bootup messages because my eyesight is very poor.I hit <ctrl s> to pause the output so I can read some details. If I do this late in the init sequence - it often briefly stops the output then the screen disappears under a blue wash (presumably something to do with the GUI login screen ot screensaver??)but the login screen never appears. Also it seems that the script never completes because the imap, webmin and http servers don't appear to have started.
I haven't found any satisfactory way out of it. I can't get back to a console terminal (I've tried ctrl c, d, z, etc.). As luck would have it the nx server has started so I can open an nx session. If I open a terminal in an nx session as root.I can't do a normal restart (shutdown -r now). Nothing happens presumably it can't run the init script because it is still running.The only way I have found to get the system back to life is to run "shutdown -r -n now" in the nx terminal session.There are probably better ways out of this predicament that I am unaware of. Otherwise it is probably somewhere between an annoyance and a bug. I would be interested in any advice the centos "board" may have as to whether this is worth raising as a redhat bug.
I've been dual booting 10.10 with Windows7 for about a month. Today is the first time I've encountered a serious problem.
This morning, nothing functioned properly after trying to open several programs. The computer seemed to be "frozen", although the mouse was working fine.
I decided to reboot, but then encountered an even bigger problem.
It failed to boot and got this message: no init found. try passing init= bootarg
The problem now is that it requires a Live CD session and I keep getting this: GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0)
In case it matters, I didn't install 10.10 from an ISO, I just upgraded from 10.04.
Ubuntu 9.10 will not boot! System froze this morning, I restarted and it is now failing to boot. Starts loading grub and I get this message:
mount: mounting /dev/disk/by-uuid/04aa3697-7bc0-45b5-b86a-77a1e6534bd5 on /root failed: invalid argument

I booted with 9.04 LiveCD discovered the drive could not be mounted-ran fsck -ln and it told me the drive has no valid partition table. I have had intermittent problems mounting flash drives before this, so I'm kind of worried it might be a hardware issue.Also have files on that drive I would rather not lose, so reinstalling is hopefully a last resort.
I have a Lenovo X60 with Intel Centrino Duo Core @ 1.83GHz 1.83GHz, and 0.99 GB of RAM. I am running a dual boot with Windows XP SP3 and the latest version of Ubuntu desktop. My problem is that after I ran the Defrag my C: drive in Windows, I can into my ubuntu.I was greeted with the following error message when i tried to boot into ubuntu {Target file system doesn't have /sbin/init}

While I was using my computer a few days ago, the terminal stopped working properly, so I tried to reboot, and when it started up again it wouldn't boot and said "no init found. try passing init=bootarg"
This has happened twice before, so I really need to figure out what keeps happening, otherwise I can't continue to use linux. i reinstalled both times before. i think that this is caused by a process that prevents me from using the hard drive, because when I try to check the disk in the terminal or in gparted, it says Device or resource busy while trying to open /dev/sda1. Filesystem mounted or opened exclusively by another program?
Also, in the disk utility, in the lower right corner of the filesystem it has a spinning "loading wheel".(i'm not sure if that means anything)
I am using ubuntu 10.10, but am not sure what kernel I am using, but i tried a few different kernel options(there's three of them at start up). safe mode does not work either.
When I try to boot in to Ubuntu (10.10) 64x I get the error "target system doesn't have /sbin/init" Then busy box comes up.

View 3 Replies View RelatedOur system has a large number of init scripts (over 180). When we reboot it, we need it to be reachable over the network before all the init scripts load, so putting the routes in rc.local does not work. What's the best place to put the routes so that they get added as soon as possibe?
