[Koha-devel] Repack git repo

[Jonathan Druart]

My feeling would be to:
0. stop pushing to the repo, so wait for the RM and RMaints to confirm
they are aware of the task
1. copy the original repo directory (backup, just in case)
2.`git gc --aggressive --prune=now`

I personally don't have preference about the time.
