That's something that in theory may allow you to resume the system from
and initrd script.
Basically, you write your resume device's major and minor numbers
into it as the "MAJ:MIN" string (eg. "8:3" for /dev/sda3 on my box) and the
kernel will try to read the image from this device and restore it.
It only works with partitions and the use of it us discouraged, so it's
deliberately undocumented.
Thanks, that's just different enough from what little info I had to make
what I have not work. I'm looking at resume from a non-swap location.
Only suspend2 can do this right now. The built-in swsusp can resume from a
swap file as long as it's not located on LVM.
Sounds like sispend2 is still needed, I haven't needed a suspending
kernel in a few years, and I was hoping that with suspend working in
mainline that resume would have been implemented. Sounds as if that's
not the case, my swap is RAID1, I was hoping to resume from one of the
mirrors, since they are based on a partition. No joy wit or without
/sys/power/resume, so I'll look further.
