Best use for LVM I have seen... Reducing the number of times you need to enter the LUKS pass phrase to once per boot, i.e., one LUKS containing an LVM of / and Swap so that the system can boot with one entry of the pass phrase and if you then have other partitions, such as an independent /home, /etc/crypttab can be used (with appropriately constructed and protected cryptpassphrase files).

At this point I don't even know what a LUKS pass phrase is -- is this something I'm liable to run into on a home desktop computer?
