Wondered if people could give me their opinions on chroot jailsAFAIK, chroot on linux is fundamentally insecure - look for the 'chroot-again' flaw. Last time I checked it still worked and allowed to escape.A chrooted jail without dropping privileges is vain anyway. Indeed. Which is why I prefer: http://www.suse.de/~marc/compartment.html Unlike chroot you can drop privileges in one swoop. It deserves to be mentioned in this thread.
'compartment' looks like like a separate executable, typically
invoked at the shell level.
Is there anything like this in SuSE or other *nix variations that
does something similar to this in a single, atomic system call?
