What else must be changed? you need to change both /etc/crypttab and /etc/fstab on the rescue system, and maybe even /etc/initramfs-tools/conf.d/resume. afterwards you'll have to regenerate the initramfs image. the best way to do so is to: - unlock and mount the rootfs of your rescue system to /mnt/rescue - copy /proc/modules, /proc/cmdline and /proc/devices to /mnt/rescue/proc - bind-mount /dev to /mnt/rescue/dev: 'mount -o bind /dev /mnt/rescue/dev' - chroot into /mnt/rescue/dev - modify /proc/cmdline, /etc/crypttab and /etc/fstab - run 'update-initramfs -u' this is written down from memory, i hope that i didn't forget anything. greetings, jonas
