I've been reading the section 'LUKS on LVM' in the wiki page
https://wiki.archlinux.org/index.php/Dm-crypt/Encrypting_an_entire_system
and there's something I fail to understand.
Under 'Preparing the logical volumes', there is:
# lvcreate -L 500M -n tmp MyVol
(which isn't shown in the ascii picture just above).
Later, under 'Configuring fstab and crypttab' a tmpfs is created on the encrypted /tmp partition:
dev/mapper/tmp /tmp tmpfs defaults 0 0
Question: as far as I've understood, a tmpfs resides in RAM, with overflow to /swap. So why is there a logical volume for /tmp ? Or put otherwise, if /tmp is to reside on disk, why use a tmpfs ?
TIA,
