git-clone and post-checkout hook

Question

According to the manual, the post-checkout hook is run after a git checkout (just as expected) but also after a git clone (unless you pass --no-checkout).

Very well, now, considering the following:

• you don't have a local repository before a git clone
• hooks are not synced between remotes
• hooks stored in a custom template directory used with --template are copied non-executable and therefore not executed after git clone (that is actually not true as stated by Jefromi in his answer, but the hook is still not executed)

It seems impossible that a post-checkout hook ever gets executed after a git clone. Still, the githooks man page at http://git-scm.com/docs/githooks explicitely states a way to avoid it being executed, and also parameters passed in case it is executed, which would indicate it is possible to execute a custom hook after a git-clone.

So, how is it possible? I am obviously missing something here.

I suppose you could make a custom installation - rename the hooks in .../share/git-core/templates/hooks to remove the .sample suffix.

You could also make a template directory full of symlinks to a hooks directory inside the repository, (e.g. post-checkout -> ../../hooks/post-checkout). Then if the cloned repo contained that particular hook, it'd get executed.

You're right, though, in most cases it will not happen.

Edit: I just tested it, and the --template option does appear to preserve permissions, so that's a much more straight-forward way to make it happen. What'd you see to indicate that it stripped that bit?

The final say on versions: You're looking at documentation online for a newer version of git than you're using. This feature was added in dfa7a6c (clone: run post-checkout hook when checking out); git describe says this wasn't included until v1.6.2-rc2.
