fsck_ffs did not need it, but quotacheck did include it from fsck_ffs. A repocopy has now moved the fsck_ffs/preen.c file to quotacheck/preen.c quotacheck and fsck should probably use the same checkfstab() function and it should possibly live in libufs. Trouble is: they have diverged in the meantime. At least now fsck_ffs is not in the equation anymore. Sponsored by: DARPA & NAI Labs.
