Settings for minimizing repacking (and keeping 'rsync' happy)

Hi!

Some of my Git repositories have mirrors, maintained with 'rsync'. I want to have some level of repacking, so that the repositories are efficient, but I also want it to minimize it, so that 'rsync' never has to perform a big transfer for the repositories.

For example, I think it would be fine if files are repacked just once in their lifetimes, and then that resulting pack file is never repacked again. I did read the gc.bigPackThreshold and gc.autoPackLimit settings, but I don't think they would accomplish that.

Basically, what I'm describing is the behaviour of not packing files until the resulting pack would be a given size (say 10MB for example), and then never repack such ~10MB packs again, ever.

Can this be done with some Git settings? And do you foresee any kind of serious drawback or potential problem with this kind of behaviour?

Thanks!!
