Improve cleartmp in a number of aspects:

+ Use rc.subr(8) features properly. + Do the whole job of obliterating /tmp contents in find(1). + Leave lost+found and quota.{user,group} in /tmp only if root-owned. + Make the overall structure clearer by first removing the X dirs (perhaps along with the rest of /tmp) and then re-creating them. + Use "find -exec rm -rf {} +" for efficiency: each rm instance gets a chance to kill as much files in /tmp as ARG_MAX permits.

Include a somewhat hackish way to make sure that we always test the

Brooks pointed out a potential problem with disabling the X cleaning

by default, so add a new knob that is on by default, and check that knob in start_precmd so that it can run even if cleaning /tmp is not enabled. This has the advantage of not violating POLA, while still allowing the user to disable this behavior if they wish (for example on a server that will never run X).

Clear up problems with /etc/rc.d/{abi|cleanvar|cleartmp} brought

to light by the PR. Specifically, convert these three scripts into good rc.d citizens, making sure that their functionality is preserved, but the rc.d framework rules are not broken. Add support for cleanvar as a regular rc.d script in the default rc.conf, and document this in the man page. Add a descriptive comment to rc.conf that regarding the three emulation/compatibility services provided by abi so users will not be confused by these services not having their own startup scripts.

Create three additional X socket directories. Using X applications when another

Overhaul the /etc/rc.d/diskless script by splitting it out into

hostname, resolve, tmp, and var scripts. The latter three are new and were repo copied. These scripts no longer depend on being booted with and NFS root instead attempt to automaticly create mfs /tmp and /var volumes if the they are not writable. This behavior can be overridden in /etc/rc.conf. Reviewed by: luigi, pjd
