This has nothing to do with lorax, if it happens in the installed system. I've looked and mtab is created by anaconda. So I guess instead of writing out our own mtab, we should just make a symlink to /proc/self/mounts, but I'm not sure if it's that easy. I think Dave will know better.

Comment 2 David Lehman 2011-01-19 18:02:42 UTC
Ondrej, since you maintain the setup package which currently owns /etc/mtab, I thought this might be of interest to you.

I don't know why we ever made our own mtab file in anaconda, so I have made a patch to switch to a symlink.

Comment 3 Ondrej Vasik 2011-01-19 19:24:56 UTC
setup package owns the /etc/mtab, but only as ghosted file. AFAIK any userspace actions with /etc/mtab are done by util-linux package(or by pre-f15 name util-linux-ng) which owns mount binary and is maintained by Karel Zak.

I don't believe this issue qualifies as a Alpha release blocker, in fact I think this might be more appropriate for the Final release.  However, I'm adding this to 'F15Alpha' so we can review the use cases that may be impacted by this bug.
