So I have a flash drive that I installed SuSE 9.1 on. Works nice. So far I
have sound and WLAN working, and tweaked it a bit to minimize writes. But
I'd like suspend-to-disk, or at least suspend-to-RAM.
I was poking through the kernel compilation options today and ran across
[ ] Software Suspend
Sounds good; I'll try it. Hit "y"...
() Default resume partition (NEW)
Hmm, OK, now IIRC there's the option to compress the RAM before it's
written. How much does RAM typically compress? "gzip -9v < /proc/kcore >
/dev/null" says 80-something percent. (Is that typical? Does swsusp use
significantly worse compression than "gzip -9"?) So a 0.25 GB partition
ought to hold 1 GB of RAM after compression.
Now, it also says "The partition ... should be a valid swap partition (at
least for now)". This is a flash drive, no swap. Can I still use this? Or
can I just "mkswap /dev/sda4" but not "swapon /dev/sda4" and not enter it
into /etc/fstab with type "swap"?
