Description Warren Togami 2009-09-09 19:33:34 UTC

Bug #518164 exposed an issue during initscripts because it no longer checks /proc/mounts to determine if /selinux is really selinuxfs.

[root@newcaprica i386]# ls -l selinux/
total 16

This fake /selinux is leftover from livecd-tools' creator.py as run via a subclassed ImageCreator class.  It is failing to clean up the fake /selinux.  This might have broken anytime in the last 2 years (or might have been there forever), but we never noticed any problem because initscripts didn't look at a fake /selinux before.

This currently breaks systems like NFS netboot where it is impossible to use selinux.

Interesting, the fake /selinux is within yesterday's nightly LiveCD image too.

Comment 2 Jesse Keating 2009-09-18 16:51:04 UTC

I'll look at patching this soon.

Comment 3 Warren Togami 2009-09-18 22:20:07 UTC

Fixed in livecd-tools-027
