How to disable timeout of password prompt for partition decryption during boot?

Question

I have a computer running OpenSUSE 12.1, 64-bit, default install.

How it works currently:

1. I turn on the computer
2. It goes through the boot process
3. At some point during boot, I am asked for password to decrypt an encrypted partition

The problem is there is a timeout on this prompt, so I have to sit next to computer and pay attention to what is going on.

How can I disable that timer, so I could for example turn the computer on and go away, and then return after 1 hour and still see this prompt?

Have a look at this Opensuse forum thread. It reveals that it's an issue with systemd's default unit timeout and not respecting the timeout setting in crypttab.

It also provides a workaround -- letting the initrd take care of it, with an /etc/crypttab entry like this (i.e. adding the initrd)

cr_sdb3         /dev/disk/by-id/ata-SHORTENED-part3 none       initrd

followed by rebuilding with mkinitrd.

Additionally, the author of the linked post filed a bug report.
