Subject: cleanup-mounts-under: Don't fail when /proc/mounts isn't readable
X-Git-Url: https://arthur.barton.de/cgi-bin/gitweb.cgi?p=bup.git;a=commitdiff_plain;h=refs%2Fheads%2Fcleanup-mounts-under

cleanup-mounts-under: Don't fail when /proc/mounts isn't readable

Not all operating systems provide a "/proc/mounts" file (for exmaple,
Darwin/OS X doesn't), so ignore this error for now ...

This doesn't solve the problem per se but makes "make clean" usable
on those systems again.
