cryptsetup uses some arguments on the "findfs" binary that Busybox
doesn't support. For this the binary from util-linux has always been
used which was pulled in anyway, but since recently has been moved to
util-linux-misc which is not pulled in automatically. This meant any
volumes set to be decrypted via /etc/conf.d/dmcrypt using UUID's or
PARTUUID's to find the right partition failed to decrypt
CC @jirutka, was findfs meant to be moved between (sub)packages?
