Hello:

Since V2 creates git shards automatically, I suggest there should be a 
way to tell it to install some set of default hooks in all new git repos 
it creates. The easiest would be by using a skel dir and specifying it 
in PI_CONFIG:

[publicinbox]
  githooksskel=/usr/share/public-inbox/hooks

We currently do it via a cronjob, but unless we run it very frequently, 
there's a delay between when a new shard is created and when we add the 
hooks to it.

Best,
-K
