it if flags were explicitly specified on the command line. Do not warn
if we were merely trying to preserve flags or remove UF_NODUMP. NFS does
not support flags.
I'm not sure that this is ideal, but it should do for now. Installing
a plain file onto a NFS server must work, we used to silently ignore the
attempt. Doing a binary install looses the flags anyway since cpio
doens't preserve them with the cdrom/network images.
XXX make world should not use flags or chown/chgrp in the obj/tmp area.
This is based on a suggestion from Ken Merry <ken@plutotech.com>.
handy at the moment with -current's mmap+unlink interactions.. The
problems seem worst when using INSTALL="install -C" in /etc/make.conf.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been

- Update man page to reflect this
- Update usage string
-d meaning creat directory is specifically not implemented by these changes.
allow the user to install using a Numeric GID or UID.
this brings it in to line with chgrp and chown, ans is required
by some people using FreeBSD in a product.

time of the source if the target doesn't exists or is different from
the source.
Use library err() functions instead of our own and pass them better
exit codes.
