Comment 7 for bug 432785

Hi!

I upgraded from 9.04 to 10.04 and hit this, using a vanilla kernel (2.6.34) and
a luks-encrypted swap.

I'm using the following workaround, which seems to work. I thought I should
paste it here in case anyone is in a similar situation and wants to give it a try.

 - Put the contents below in /etc/initramfs-tools/scripts/local-top/encrypted_swap,
   replacing /dev/sda2 with the disk your swap is on, and swap-crypt with the
   device-mapper name of your swap disk (must match the one used in
   /etc/crypttab and /etc/fstab):

---------- 8< ---------- 8< ---------- 8< ---------- 8< ---------- 8< ---------- 8< ----------
#!/bin/sh

PREREQ=""

prereqs()
{
        echo "$PREREQ"
}

case $1 in
# get pre-requisites
prereqs)
        prereqs
        exit 0
        ;;
esac

# extracted from cryptroot
udev_settle()
{
        # Wait for udev to be ready, see https://launchpad.net/bugs/85640
        if [ -x /sbin/udevadm ]; then
                /sbin/udevadm settle --timeout=30
        elif [ -x /sbin/udevsettle ]; then
                /sbin/udevsettle --timeout=30
        fi
        return 0
}

udev_settle

# Replace "/dev/sda2" with your device, and "swap-crypt" with the
# device-mapper name, which can be found in /etc/crypttab or /etc/fstab

/sbin/cryptsetup luksOpen /dev/sda2 swap-crypt

---------- 8< ---------- 8< ---------- 8< ---------- 8< ---------- 8< ---------- 8< ----------

 - chmod +x /etc/initramfs-tools/scripts/local-top/encrypted_swap
 - Rebuild your initramfs using update-initramfs

Thanks,
