Yes, it's possible to read in the passphrase once and then feed it on
the command line using -p,  it's also possible to feed it on stdin
w/ a patch I've posted previously.

The only issue with reading in passwords from a shell script is to
not echo to the tty.  There are ways around this problem such as:

In bash you can use:
	read -esp "Enter passphrase: " pass
	gbde attach $dev -l $lck -p $pass

otherwise:
	tmp=3D`stty -g`; stty -echo
	read -p "Enter passphrase: " pass
        echo; stty $tmp
	gbde attach $dev -l $lck -p $pass

You could put this into your rc.early or something similarly early
in the boot sequence if it suits your needs.  (For security reasons
passing the passphrase on the command line should be done before
going multiuser.)

Hope this helps,
