Warner Losh c42073b2d4 Back out 1.143 and 1.144. They are no longer needed now that we start
devd later in the boot process.  This should fix all the problems
people have had with those commits.  Diskless should be working again,
and those that mount /usr with nfs should be able to do that again too.
