Well, the "easy" solution is to just increase the value
of NNAMELEN and rebuild everything from sources to use
the modified sys/mount.h. (If you can run a modified
system built entirely from sources, I think you can do
this.)

However, this can't be done in -current because it breaks
the statfs(2) syscall API, etc.

There is a patch in projects/ino64 to try and change ino_t
to 64bits and I think it also included changes for this.
- It would need a new statfs(2) syscall and versioned library
  routines for everything that uses statfs(2) in libc, etc.

So, for -current the answer is "it is not easy".

There was a patch floating around that truncated the path
to 64bits, so that the mounts are allowed but not reported
correctly via statfs(2). You can probably find that patch
and use it, if a broken statfs(2) isn't a problem for you.
