I'm a heavy user of this myself. It's especially useful because you can just have a single luks encrypted ext4 without a lvm in between for a swap partition or (even more yuck) using a separate (encrypted) swap partition. Arch does support this, mostly because as far as I know, the resume_offset= is consumed by the kernel, while resume= has to refer to the (unencrypted) filesystem (/dev/mapper/root in my case). So, as long as this solution waits for the device to show up in /dev/ (and especially /dev/mapper/ for my case), this should work out. Here's information to set this up. Imho more people should be aware this is possible: https://wiki.archlinux.org/index.php/Suspend#Hibernation_into_swap_file Jan _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
