Hello,
I've been having a bit of a time with this install. I have the whole root filesystem on an encrypted LVM group. When I boot, I'm prompted for the password and the luks container is decrypted, but only root an swap are mounted. I get errors about the other partitions, which cause the system to break, including portage.
My fstab is as follows:
# <fs> <mountpoint> <type> <opts> <dump/pass>
/dev/sdb1 /boot ext2 noauto,noatime 1 2
UUID=7e35db9b-f5f7-4bb3-98e1-1466f56ed9b1
