Slow cruise to Nevada

Despite having a very hectic week, I finally finished a Live Update on my Solaris partition and have enscripted it, so it shouldn't be so hard next time. I had to fix my zfs checkpointing routines as while I had turned it on to protect my work against stupidity, I wasn't deleting them. I have amended the Gnome startup scripts to invoke $HOME/.gnome.login and the .gnome.logout is also invoked appropriately, and .gnome.logout creates a snapshot. The main reason for doing this is that I am unsure that Gnome runs the login shells exit scripts, and not all shells have these. However my poor code also means that root won't start a JDS session any more. I am going to claim this as a security enhancement.
My interest and use of ZFS and Live Update has all been inspired by Chris Gerhard who documents his ideas at The dot in ...---... Live Update is also a coming technology, so I think it's important for me to get to grips with it.
I am now considering how to write a tcl/tk wrapper for my LU script as I am still a number of versions behind.This meant I still had to amend the grub menu.lst by hand and refresh the boot archive manually. (The latter requirement may have been caused by me, but now I know how easy it is to mount the shadow BE, I shan't leave it for so long again.) I must remember that the reboot command is probably best issued from a root failsafe session.
