Well, there may be reasons why someone would want to not have tail,
but that's not the same question as "Why mountpoint.c", especially
considering that your implementation is both broken due to various
races (the stat/ lstat calls, for instance), needlessly
inefficient (pointless memory allocations) and does some stuff which
is hardly useful (like printing a single \n with printf
(putchar, anyone?) when told to be quiet) and does some things which
are just weird (why the 'stat/lstat'-combination)?
