I used "freebsd-update upgrade -r 8.0-RELEASE" and all went well for the
usual first install of the kernel with "freebsd-update install". After
rebooting into single user mode, I manually mounted the ZFS partitions
(which needs to be done as follows since the ZFS userland tools are
incompatible with 8.0):
mount -uw /
mount -t zfs tank/usr /usr
mount -t zfs tank/var /var
mount -t zfs tank/tmp /tmp
mount /bootdir
Then I ran "freebsd-update install" for the second time to install the
userland. The disk lights flashed a lot at the start, but then the
system came to an almost complete halt.
Looking at 'systat -vmstat' I can see that the disk and cpu are both
almost idle. 'top' doesn't work (since it probably is the old userland).
'ps ax' shows that freebsd-install is running and has spawned an
'install' command. It is installing files at the rate of about one per 5
minutes. At this rate it should be done by next Christmas.
I can see that the files it completes have their modified date changed
to the current date. There is nothing interesting in /var/log/messages.
It is still working, and I don't want to kill it for fear of ending up
with a completely non-functional system. Any thoughts about this
problem? I'm really stumped.
Just for the archives... the problem was a non-functional LDAP. I had thought
that in single user mode nsswitch was bypassed, but I was wrong and the
(non-running) LDAP server was being queried for every 'install'. The timeout (5
minutes?) was the delay before it then proceeded to the next file.
