MNT_MNTTAB was lifted from Unix header files.  Some Unix-born
program could expect that to be a compile-time string.

If the only reason is to allow adding filesystems with `addmntent',
then does it really need to be a file?  Why not keep it in memory
while the program runs?  Do we have any reasons to leave it there
after the program exits?  It surely will have one effect that could
surprise people: programs run after the file was created will see
those fake filesystems which they probably cannot access.

I think that any effect of FSEXT extensions should not be permamenent.
It should only hold as long as the program which creates the
illusionary files/filesystems runs, and disappear immediately after
that.
