Hi,

that might be one way, but I don't know if there are any problems if frozen
programs have open files on /tmp or /var, since the processes are resumed before
any run-level scripts (?).
Maybe I am missing something, but if you have /tmp and /var as (size-restricted)
tmpfs's when you create the image in the first place, what is the problem with that?

best regards

Torsten
