Re: [PATCH] t/lib-git.sh: fix ACL-related permissions failure

Fabian Stelzer [off-list ref] writes:

The problem is that the ssh-keygen in the layz_prereq will succeed but
might create a private key with world readable permissions. Only the
remaining tests using this key will then fail with a "your private key
permissions are too restrictive" like error. If we would like to make
sure in the prereq that the keys actually work fine we would need to do
a signing operation with them in it.

That sounds like a right thing to do, with or without the setfacl fix.

Something like the following call would be enough:
echo "test" | ssh-keygen -Y sign -f $GPGSSHKEY_PRIMARY -n "git" 
Not sure if we want to go that far though. The setfacl seems fine to me
otherwise.
