[SOLVED] udev-120 and dmcrypt

[jakeluck]

just did a update world today and I noticed that my encrypted swap that was
working previously had stopped loading. i have already unmasked and upgraded
to newest udev-120, same kernel 2.6.23-gentoo-r3 on amd64

CONFIG_BLK_DEV_LOOP=y
CONFIG_BLK_DEV_CRYPTOLOOP=y
CONFIG_BLK_DEV_NBD=y
CONFIG_MD=y
CONFIG_BLK_DEV_DM=y
CONFIG_DM_CRYPT=y
CONFIG_CRYPTO=y
and most of the CONFIG_CRYPTO_* are on

/etc/conf.d/cryptfs
swap=csb source='/dev/sdb5'
swap=csc source='/dev/sdc5'

/etc/fstab
#/dev/sdb5 none swap sw,pri=3 0 0
#/dev/sdc5 none swap sw,pri=3 0 0
/dev/mapper/csb none swap sw,pri=3 0 0
/dev/mapper/csc none swap sw,pri=3 0 0

# swapon -a
swapon: cannot canonicalize /dev/mapper/csb: No such file or directory
swapon: cannot stat /dev/mapper/csb: No such file or directory
swapon: cannot canonicalize /dev/mapper/csc: No such file or directory
swapon: cannot stat /dev/mapper/csc: No such file or directory

suggestions?

This is more then likely caused by an upgrade of cryptsetup. You need to copy the contents of /etc/conf.d/cryptfs to /etc/conf.d/dmcrypt as the config file for cryptsetup has changed name.
ie
swap=csb source='/dev/sdb5'
swap=csc source='/dev/sdc5'
should be in /etc/conf.d/dmcrypt and not /etc/conf.d/cryptfs

If this works then you can delete /etc/conf.d/cryptfs.
