Public bug reported:
I have following configuration (Desktop): (ubuntu64)
/dev/sdd2 ext4 -> /boot
/dev/sdd1 extended
/dev/sdd5 LUKS Encryption
/dev/mapper/sdd5_crypt LVM2 -> /dev/SSD
/dev/sdc1 LUKS Encryption
/dev/mapper/sdc1_crypt LVM2 -> /dev/Private
/dev/sdb1 extended
/dev/sdb5 LUKS Encryption
/dev/mapper/sdb5_crypt LVM2 -> /dev/Private
/dev/SSD/Home ext4
/dev/SSD/System ext4
/dev/Private/Documents ext4
sdc1_crypt and sdb5_crypt can be unlockt via a derived key from
sdd5_crypt.
This was always hard to set up under ubuntu especially /etc/crypttab wasn't
creating itself. But with the alternat insatller it was possible to set up
Linux this way. With the new isntaller in 12.10 it doesn't work anymore. I
needed to go back one release and update, but this makes my system Instabil.
Once I tried the Fedora Installer, it recognized all of my LUKS Devices and
LVMs and displayed them in a way one can understand it. Even easier then the
alternate installer in 12.04. The Installer even created /etc/crypttab with
# sdb5_crypt UUID=xxx sdd5_crypt
luks,keyscript=/lib/cryptsetup/scripts/decrypt_derived
which I allways hat to create manually in Ubuntu after the Installation was
done.
So with 12.10, even if I get the encrypted volumes to work with the installer
(thats not easy) the installed Ubuntu afterwards wont start.
At least the functionality of the alternate installer for 13.04 would be nice,
but even nicer would be an installer as easy as the fedora one for crypt+lvm.
I have following configuration (Netbook): (ubuntu32)
/dev/sda1 ext4 -> /boot
/dev/sda2 extended
/dev/sda5 LUKS Encryption
/dev/mapper/sda5_crypt LVM2 -> /dev/netbook
/dev/netbook/System ext4
/dev/netbook/Home ext4
With this configuration I couldn't even unlock the encrypted volume to
get to the LVM to mount one of my drives "System" or "Home". This also
was set up using the alternate installer and now its not possible to
make a clean installation with 12.10 (which I would because upgrade
broke my wireless, just a fact on the side).
Hopefully this confiuration details can help you reproducing my bugs.
