Set up LVM on my home box, partly as a learning exercise (HP LVM, which I use at work, is almost identical to Linux LVM) and partly to be able to grow filesystems without having to resort to symlink nastiness or the like. e2fsadm -L+40G /dev/vg00/home, mmm :)
I set up / as RAID1 instead of LVM, though.
