If you're using squashfs, maybe syncing shouldn't be done via git anyway but instead via some mechanism using the squashfs images we distribute?

No difference if you sync as root, right?

That would be both slower and imply 24 hour delay, so no.

Doubt it.  Don't want to break ownership all over the place just to try.
