Looking at /usr/include/ufs/ufs/dinode.h, which seems to describe
the format of the on-disk inode I see that di_nlink is a int16_t,
for which the largest positive value is 32767. If you try increasing
this things will almost certainly blow up.

You really don't want to have a directory with 32K entries on a
UFS filesystem - it will be painfully slow and inefficient. I've
tried to clean up a news filesystem which had directories with
large numbers of entries and you can only delete entries once every
few seconds - in the end I unmounted the filesystem, clried the
directory and fscked.
