[DC LoCo] Upgrade from 10.10 -> 11.04 took two days to recover from

[N.C. Weber]

I think it's things like that is the reason Mint doesn't allow OS version upgrades. They want you to back-up you home folder and do a fresh install. Personally, I doubt I would put with that nonsense from Mint.

I built 10.10 with LVM on DMRAID because GRUB2 lets you boot from that without any /boot filesystems.

I upgraded to 11.04 and *kaboom*

Eventually I found LP: #770600  "22_add_pdc_64bit_addressing.patch: breaks some pdc raid sets"

I installed the PPA with the newer version of DMRAID while in a chroot booted of a Gentoo amd64 stage1.  Had to remember how to

dmraid -ay
pvchange -xy /dev/mapper/pdc_xxxxxxxxxx1
vgchange -ay
mount /dev/vg0/lv0 /a
mount -t proc proc /a/proc
mount -o bind /dev /a/dev
mount -t devpts devpts /a/dev/pts
mount -o bind /sys /a/sys
chroot /a

etc. to activate the PDC DMRAID RAID1 ("fakeraid") and mount it get into the chroot.

A minor additional glitch was that a symlink from /etc/dhcp -> dhcp3 crapped out the installation of samba (which I don't use but ubuntu-desktop insists on.)  Once that symlink was removed the packages installed.
