I’ve had a spare data cruncher (Dell Precision 479 Xeon 2.8) sitting under my desk for awhile. Not being terribly interested in OpenBSD that it came to me with (sorry Eric), I blew it away and installed Ubuntu 8.04 Hardy Heron x86_64. It seems quite stable and is perhaps quicker than 7.10. That isn’t my point, though.

This weekend I installed the 32 bit version on a Dell Inspiron and it seemed to due the laptop good. Resume from sleep is definitely faster. Today I thought I’d take a real leap and upgrade in-place my 64 bit Thinkpad T60. I didn’t want to have to fool around with configuring LVM and associated encryption so I thought I’d just sudo update-manager -c -d to upgrade to the Hardy Heron Beta.  I’m happy to report that everything seems to work fine.  I was a little nervous on first reboot while waiting for a sign that dm-crypt was working.  After entering my dm-crypt password I noticed that there was a ext3 drive check in progress.  It was subtle compared to the same process in Gutsy since it didn’t drop out of the gui to do it.

Everything seems to work fine.  Audio, DVD, VPN, all work fine.  Sleep and resume seem considerably faster though on first resume my wireless card wasn’t found.  Hope that gets fixed.  Also, I’m happy that wake-on-lan works on all of the machines I’ve tested so far, which wasn’t the case in Gutsy.  Several machines would wake in Windows, but not in Linux, which was a bummer.  I don’t consider myself lazy, but wake-on-lan is awesome.  I hope that it works with dd-wrt so I can wake my home desktop remotely.

So, be it here known that it is possible to in-place upgrade an LVM/dm-crypt encrypted machine from 7.10 Gutsy Gibbon to 8.04 Hardy Heron.
