The git package ships with a number of sample hook files. These are shell scripts and therefore the #!/bin/sh line gets substituted at build time. However these files get installed into every git repostory that is created, and users are invited to use them as templates for their own hooks. This will be fine until both git and bash are updated. Now the original bash is free to be garbage collected. If that happens, the path: #!/gnu/store/qkw4zrwfybxww8f56nkb6hggxambk89b-bash-4.4.0/bin/sh will no longer exist. I suggest what we turn off the shebang patching for the files in share/templates for git. J' -- Avoid eavesdropping. Send strong encrypted email.
