On one of my FreeBSD boxes (2.2.6-R) all user home directories are
NFS-imported without root access (root mapped to nobody). Login fails (`no
home directory') if the user doesn't give at least mode 755 to his/her
home. I modified login.c to overcome this. I don't know whether my
modification is really bug-free, and I don't know whether this problem has
already been fixed in 2.2-stable or 3.0-current. In any case it would
be nice to find the problem fixed in the future ...
Here's the diff listing concerning my modification of login.c:
