The interaction between installboot and the secure mode is a major
pain in the butt. Whenever I install a newer version of current, I'll
snapshot the running root and /usr via a newfs, installboot, tar |
tar, and finally a cd /usr/src , make build. This has te advantage of
building a snapshot with a current filesystem and new bootblocks on
the snapshot disk partitions. With the "secure" mode, one can't do
this while I'm running multiuser any more.
Would it be possible for installboot to temporarily unmount the disk
partition so that it could write to the raw partition "securely"? I'm
somewhat reluctant to turn secure off in my config file.
