[CRIU] Dump Process

[Thouraya TH]

As i said, i can't, for the moment, test the restore process on a new
machine.


*Not only. You also have to make sure that files that are in use by your
processes are available on the other machine.*

Input files for example: i have to save them
In the same directory where i saved img files (imgDir in my case) ? can you
give me some details please ?

Thanks a lot.
Bests.
