For example, something like the following, which checks /etc/mtab is a symlink
on Linux and attempts to create one to /proc/mounts if the conditions are
correct. Just in case initscripts postinst maintainer scripts cannot create
the symlink, because possibly the package was upgraded/installed offline and
/proc was not mounted.
Also clear out devfs stuff, which is afaik no longer supported.
