I have decided to give encryption a shot and I have started with some
bootable usb disks I have as emergency/recovery media.

Everything works and partitions seem to mount just fine, but during boot
in the fsck fase, root is apparently checked twice and home apparently
doesn't get checked.

root: clean, 177630/524288 files, 1430174/2097152 blocks
boot: clean, 34/65536 files, 50998/262144 blocks
root: clean, 12450/2162688 files, 7055618/8649728 blocks

Using dumpe2fs to check how many blocks my root and home volumes have I
can confirm that the first root line really corresponds to root and the
second root line corresponds to home.

Does anyone know if this is a (known) bug or am I missing something?

My partition/volumes setup is as follows:

boot
luks
-lvm
--root
--swap
--home

menu.lst:
title Arch Linux
root (hd0,0)
kernel /vmlinuz-linux root=/dev/lvmvol/root
cryptdevice=/dev/disk/by-uuid/d9cfc224-4ece-489b-a231-f5a5a876354f:luksvol
ro quiet
initrd /initramfs-linux.img

fstab:
UUID=b4a938a4-1a49-42dc-9535-472efcccc264 /boot ext2 defaults,noatime 0 1
/dev/lvmvol/root / ext4 defaults,noatime 0 1
/dev/lvmvol/home /home ext4 defaults,noatime 0 2
/dev/lvmvol/swap none swap defaults 0 0

mkinitcpio.conf:
MODULES=""
BINARIES=""
FILES=""
HOOKS="base udev usb usbinput keymap encrypt lvm2 autodetect pata scsi
sata filesystems"

In ~4 years of using encrypted lvm, I never saw that /dev/lvmvol thing.
I can't figure how you managed to create it and use it in your
config(s). Usually is something like /dev/mapper/lvmgroup-lvmvolume. Are
you sure that LVM was created corectly? Did the system ever boot fine?

I suppose everything is fine except that your home partition has label "root".

tune2fs -L home /dev/path/to/home

It is there in LVM, not sure about encrypted LVM though. You have both
/dev/lvmgroup/lvmvolume and /dev/mapper/lvmgroup-lvmvolume. The
/dev/lvmgroup/lvmvolume is a softlink to /dev/dm-x where x is the appropriate
number.

Is the same on encrypted LVM, but the OP said /dev/lvmvol/root and so
on, which is not /dev/lvmgroup/vlmvolume.
