Mounting soft partitions from network boot?

Let’s say you hosed your root partition and have to boot from CD or network. You have data on soft partitions you need to access, which aren’t very easily accessible, because  they are…well..soft. Here’s the answer. Just import the SVM configuration from the root disk and mount it up.

# mount -o ro /dev/dsk/c0t0d0s0 /a
# cp /a/kernel/drv/md.conf /kernel/drv/md.conf
# umount /a
# update_drv -fmd
Cannot unload module: md
Will be unloaded upon reboot.
Forcing update of md.conf.
