[arch-projects] [RFC 03/23] Add warning if dependencies are missing

[Matthew Monaco]

From: Matthew Monaco <matthew.monaco at 0x01b.net>

I don't really like this, it would be better to check only for
cryptsetup here, other checks can go where they're used or not at all.

The best might be to not do anything like this at all.
