wouldn't this crypttab entry ask for a password (third entry: `none')?
My problem is that I do want to have all partitions (/, /home, wap)
encrypted and I do want to give the password only once during boot. So,
at this point we would need the name of a key-file (containing the
passphrase for /home and swap), which is accessible after the root
partition is decrypted by the password given, without further asking me
for passwords. My crypttab man page says that an entry `none' will ask
for the password interactively.
The solution suggested by Heinz works excellently in my environment. Is
there any argument AGAINST this solution - I mean, does this conflict
with some other action during boot?
As a user (rather than an expert in encryption and boot process
organization ...), I think that it would be nice to have a clear
description how to proceed which is also mentioned in the openSUSE HOWTO
pages.
