Binary package hint: ubiquity
i used Lucid's alternate kubuntu CD. for the first time, i wanted to setup root and swap encryption. for root, i used an encryption that of course requires a passphrase. for swap, i used a random key generated on boot time. the installer wrote an /etc/crypttab that contains this info.
for fixed partition encryptions, like my root, using UUIDs is possible, and is what the installer used.
but swap will be reformatted on each boot, hence, the UUID will change after every boot, so the installer used the device node (/dev/sdb3) to identify it in crypttab.
the catch? my devices change on each boot, sometimes it's sdb3, sometimes sda3, others sdc3.
the result? partition number 3 on another hard disk was used as swap, and got wiped out.
suggestion, the installer uses a /dev/disk/by-id in case of swap encryption.
i consider this bug VERY serious as to what results can come from it.
thank you.
