15 Check out userspace suspend ( It's not in
16 portage, but will do what you want since you can resume from an initrd.
17 In the initrd, you can open a network connection, mount all that stuff
18 (you never told where that looped file is located, so I guess it's on
19 r/w NFS) and then resume. It's not implemented at the moment, I think,
20 but should be easy to add ("remote suspending" is mentioned as an
21 "easy" possibility).
