upgrade 7.2 to 8.0 problems

[Aristedes Maniatis]

# AMD64, Supermicro hardware. ZFS filesystem (booting to UFS, then rest of the file system /usr /var /tmp on ZFS).

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.

Thanks
