sync flushes the contents of the disk buffers to the disk. So, if you forgot
to type sync (or logout, which also does a sync) and missed something, it's
REALLY gone, as it only was in memory.
So, although I have no experience about recompiling Minix, I'm afraid you
have to do at least the final actions again. Perhaps something you have done
was saved, because if the program update is run in the background, a sync
is done every 25 seconds.

Good luck!
