Well locally I have symlinked /etc/mtab -> /proc/mounts since:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f84e3f52
So this would not break anything for me.

Also I understand Fedora 15 will symlink /etc/mtab to /proc/mount too.

What about older kernels though?
I'm wondering should suse be considering making the symlink also,
or otherwise keeping /etc/mtab in sync?
It seems a bit like this gnulib change is doing it in the wrong place.

I've cc'd the util-linux guys who know much more about this than me.

cheers,
