Speaking of rc.d/tmp (the only thing that REQUIRE:'s tmp is rc.d/cleartmp). Yet there are rc.d scripts that use /tmp, so they probably expect rc.d/tmp and rc.d/cleartmp to have been executed before they are...but nothing REQUIRE:'s them. So, for a long time, I've been having problems where VirtualBox VMs started using rc.d/vboxheadless can't be managed. After much hair pulling, I found that it uses a directory in /tmp, and wondered why it loses track. So, I ran "rcorder -s nostart /etc/rc.d/* /usr/local/etc/rc.d/*" and found this: ... /etc/rc.d/LOGIN /usr/local/etc/rc.d/vboxwebsrv /usr/local/etc/rc.d/vboxheadless /etc/rc.d/nfsclient /etc/rc.d/amd /etc/rc.d/atm3 /etc/rc.d/auditd /etc/rc.d/auditdistd /etc/rc.d/tmp /etc/rc.d/cleartmp ... So, I added tmp to rc.d/vboxheadless's REQUIRE: line. Which has significantly changed the order of things, rc.d/tmp still happens fairly late in the startup (about midway between NETWORKING and LOGIN)....so rc.d/vboxheadless get's called after LOGIN (as it REQUIRE:'s), though DAEMON still comes after LOGIN. Doing just "rcorder -s nostart /etc/rc.d/*" has rc.d/tmp occuring about midway between NETWORKING and LOGIN, which is probably due to its "mountcritremote" requirement.
