    Ok...I've encrypted my home partition. I used the "Disk Utility" to do so. Worked out grand. Now if I run

    cryptsetup luksOpen /dev/md1 home

    it asks me for a passphrase and the device appears for mounting. Grand.

    So now I want it to ask for my passphrase at boot time. My /etc/crypttab looks like this:

    # <target name> <source device> <key file> <options>
    home /dev/md1 none luks


    No dice. When I run

    cryptdisks_start home

    I get this:
    * Starting crypto disk...                                                       * home (starting)..
/usr/sbin/cryptdisks_start: 1: /lib/udev/watershed: not found
/usr/sbin/cryptdisks_start: 1: /lib/udev/watershed: not found
/usr/sbin/cryptdisks_start: 1: /lib/udev/watershed: not found
 * home (failed)...                                                      [fail]

    Can someone tell me what I'm doing wrong there?

    I'll leave this here in case it happens to someone else....it prompts for the password at reboot. Looks like cryptdisks_start is just broken.

    Encrypted home partition. \o/

    [HTML]parted -s /dev/sda mkpart logical ext2 15800 15900
    mkfs -t ext2 /dev/sda4

    cryptsetup --verbose --verify-passphrase luksFormat /dev/sda4
    cryptsetup luksOpen /dev/sda4 sda4
    ls -l /dev/mapper
    mkfs -t ext3 /dev/mapper/sda4

    mkdir /secure
    mount /dev/mapper/sda4 /secure

    echo "sda4 /dev/sda4 none" >> /etc/crypttab
    echo "/dev/mapper/sda4 /secure ext3 defaults 1 2" >> /etc/fstab
    shutdown -r now[/HTML]
