There shouldn't be a dependency of 'tmp' on remote filesystems. Discussed this with Brooks and he can't find evidence that provoked the change in 2005. If anything gets broken I will fix it in a different way, not via rc sequence change.This is because /etc/rc.d/tmp has this line: if ! /bin/df /tmp | grep -q "^/dev/md[0-9].* /tmp"; then and when your doing NFS boots with seperate /usr you do not have /usr/bin/grep to run that line. Almost always the reason things have a REQUIRE: mountcritremote is that they use some commands from /usr.
This dependency on /usr/bin/grep is easily removed, see:
