I've done 'make world' in both single user mode and multi user
. One thing to watch is that the /usr/libexec/ld.so file gets
updated. The last time I did 'make world' in multi user mode it
didn't. I tend to 'ls -lt' in the standard directories to check
on what didn't get updated.
Probably the best way is...
In multi user mode:
# (cd /usr/obj ; chflags -R noschg usr ; rm -rf usr)
# cd /usr/src ; make includes
# make buildworld
In single user mode:
# make installworld
# cd /sys/i386/conf ; config KERNELFILE
# cd ../../compile/KERNELFILE ; make kernel install
For a machine where uptime isn't critical I just shutdown to
single user mode and do the entire sequence.
Of course you can't do single user mode remotely so the only
way is to do the entire upgrade from multi user mode. Just check
on the files that don't get updated and copy them over from the
/usr/obj directories. To update ld.so was a bit tricky. I used.
# cp /usr/obj/.../ld.so ld.so.new
# chown bin.bin ld.so.new
# chflags noschg ld.so
# ln ld.so ld.so.old
# ln -f ld.so.new ld.so
# rm ld.so.new
# chflags noschg ld.so
Then reboot and delete ld.so.old.
Cheers.
