# we add a generous list of filesystems to include. This also helps with
# recovery situation as including e.g. the vfat module might help a user
# who needs to create a new cryptkey (using a backup of a keyfile) on
# a windows-machine for example.
# This list needs to be kept in sync with the one defined in passdev.c
