In order to do debugging on mp3tofid development, I need to quickly switch between v3alpha versions 3, 5 and 7. Doing a full upgrade (or downgrade) is slow and wipes out custom changes.

Is it safe to use mlord's upgrader tool to just extract the /empeg tree of each v3alpha image file and just replace these trees on the empeg, rather than doing a full upgrade/downgrade?

I didn't notice any other differences outside this tree in the hda5 filesystems of these versions, but there may be something other critical step in the upgrade.

Thanks,
Pim
