Re: xenial: Watch out for boot failures due to /etc/mtab file

Existing installs should be fine, this is exclusively to find
installer bugs, i. e. broken /etc/mtab *before* the first boot of
installed Ubuntu (as we fix /etc/mtab on each boot).

It could of course be that something changes /etc/mtab back from a
symlink to a file while Ubuntu runs, then the next reboot would do
this as well. We had one really funny/scary bug in the past:
http://launchpadlibrarian.net/197406177/lxcfs_0.5-0ubuntu1_0.5-0ubuntu2.diff.gz

So if you find something like this during upgrades, please do tell me.
However, I haven't found or heard of anything so far, and boo-boos
like the above are hopefully rare.

Thanks,

Martin
