In fact I use the same trick as for ROOTFS_DEVICE_TABLES: whether
ROOTFS_USERS_TABLE is 'foo' or 'foo bar quux', the invocation of `cat` is
valid, as `cat` takes a list of filenames as arguments. So no need to loop
on a list. Or is the loop preferred because of portability issues?

But it is true that I should use the plural form ROOTFS_USERS_TABLES.

Thanks for your review.
