Slackware :: Building Packages, Not Running An Alternate Operating System Or A Service Such As Ssh?

I have been playing with chroot to build packages.I am wondering about the limits or caveats of using chroot to mix operating systems. For example, what should I beware if I use 12.2 and chroot a 13.1 system? Or if I use 13.1 and chroot a 12.2 system? After all, the chroot does inherit some attributes of the parent system.There is the noticeable difference of kernel versions. For that one reason I'm thinking that mixing system versions might be frustrating.

My focus is building packages, not running an alternate operating system or a service such as ssh. I realize that building packages as root in a chroot potentially compromises security but that is not my focus.I am aware that a chroot is not a true virtual system.A virtual machine is an option, but in this thread I'm curious about the limitations of chroot. I find building packages in my virtual machines much slower than actual hardware, even with a dual core. Hence my interest in chroot
