It is on another disc, with OS that has problems (F24 does not boot
beyond single user mode, Network Manager doesn't start) after removing
power / battery while in "suspend to RAM".

Thats why I think about setting 9.5 on my current machine (F30/PG11
cluster) and then do a dump, only I need to know how to do it (binaries
/ libs / default cfg + data copy).
