Re: Limiting mount point to known cells

Hi,

There was a thread about /afs/.git hanging back in 2014 which ended up 
with a work around from Jonathan Billings:

https://lists.openafs.org/pipermail/openafs-info/2014-August/040888.html

Basically, he suggested setting GIT_CEILING_DIRECTORIES ( 
https://git-scm.com/docs/git/2.35.2#Documentation/git.txt-codeGITCEILINGDIRECTORIEScode 
) environmental variable and limit git's search.

In the same thread, a blacklist (or whitelist) of cell names was 
suggested to prevent afsdb queries for troublesome domains but it seems 
it never got implemented.

-K.
