Libguestfs - Feb 2011 - [PATCH] appliance: Force /etc/mtab to be a symlink to /proc/mounts

I'm currently testing this patch on Rawhide, F14, Debian and Ubuntu.

It's required to fix Rawhide at the moment, so I'm going to add this
patch to the Rawhide SRPM.

An alternative fix would be to change the daemon to always parse
'/proc/mounts'.  I'm not really sure which is better.

Rich.

Subject: [PATCH] appliance: Force /etc/mtab to be a symlink to /proc/mounts

Since Fedora util-linux 2.19, the %post script has done:

  rm -f /etc/mtab
  ln -s /proc/mounts /etc/mtab

We now parse /etc/mtab, and it seems to be a good idea in
general to make it work like this.
