i have been wondering for years why does it have to exist at all, if it
is only a symlink anyway, why cant apps/services not directly
use /proc/self/mounts ? could we perhaps get completely rid of mtab and
all the pain it brings along ? (i know this would be a huge project
indeed, but it seems a lot cleaner as an end-result)
