I just started to think about implementing…
# apt-get snapshot
Cloning the root file system
to syspool/backup-2007-06-26:17:50
Please use /sbin/update-grub to refresh
the list of available boot environments
…when I found the post about playing with the ZFS boot on NexentaCP envisioning the very same idea.
Guys, we are actually very close to implementing this on Nexenta Operating System. Allmost all the bits and pieces are in place.
The only thing that is missing for me is the ability to override the bootfs property from the GRUB bootloader, so that you don’t need to specify where to boot from as the pool’s property:
zpool set bootfs=syspool/myrootfs syspool
Anyways, this is going to be very exciting, because it will solve the non-existence of the backout option that I have been hearing about many times as being the major drawback of the Debian’s package management system.

The seventh annual Debian Conference has been organized in the beautiful city of Edinburgh. And not only that, the conference venue is located just next to the city center, in a old comfortable and friendly place that has got its own atmosphere.
I have met here a lot of really interesting (and famous - in the world of Debian/GNU Linux) people. My impression is that the atmosphere was just amazing, very friendly, open, productive, …. Well, we had some discussions about various license related issues, but as long as we behave as rational people and as long as there exists a common sense I’m not worried.
The picture above shows Tom Marble of Sun and Mathias Klose of Canonical talking about how to best package various Java upstreams available on the market for Debian/GNU Linux, Ubuntu, and later I hope even for Nexenta.
I have taken a chance to present some nice OpenSolaris features like zoneadm clone smoothly integrated within Nexenta.
It’s a pitty I had no more time to spend at DebConf2007, but I’m already looking forward the DebConf2008. The videos of the presentations are becoming available one after one.
The new flash demos about pbuilder running on top ZFS powered OpenSolaris Zones (that are able to host the Debian/4.0 Etch and other Linux distros thanx to BrandZ extension) are all available at my Nexenta Pages.

I’m back from Berlin where I once again spoke about Nexenta Operating System. I have used slightly modified version of my OpenSolaris for Human Beings talk and I think it worked well. People were again smiling during the part where I present that it is normal not to support –version commandline switch in the Sun code.
There is also new flash demo available for Nexenta/Debian/Ubuntu newbies that will teach you how to modify existing Debian Package and install it from your custom private APT Repository. Check it out on my Nexenta pages.
