I use jumpstart at home to update the hosts in my lab as new Nevada builds and Solaris updates are released. As part of the unattended installation / upgrade process, I create a couple of ZFS file systems on each system. Since jumpstart doesn’t have built-in support for creating ZFS file system, I had to add the zpool and zfs commands to my finish script. After a bit of tinkering around, here is what I came up with:
# Locate the first local device on the system
DISK1=`echo quit | /usr/sbin/format 2>/dev/null | /usr/bin/awk '$0 ~ /0./ { print $2 }'`
# Create a ZFS pool using the disk device above
/usr/sbin/zpool create -f -R /a p0 ${DISK1}
# Create ZFS file systems
/usr/sbin/zfs create p0/home
/usr/sbin/zfs set mountpoint=/home p0/home
.....
This appears to work pretty well, and my boxes are now built and operational once the jumpstart process completes. Niiiiiiiice!
