Which could be evil without resumable clone on a big repo.
git clone --bare will work though.

I like (2) a bit more too, and give a hint about explicit HEAD fetching.

I tried to hack it through via adding HEAD:HEADtmp static const
refspec to remote.{h,c}
and hit "Ignoring funny ref 'HEAD' locally" in remote.c:get_fetch_map,
commented out that ignore and got:
error: unable to resolve reference HEAD: No such file or directory
fatal: Cannot lock the ref 'HEAD'.
from builtin/clone.c:
...
const char *head = skip_prefix(our_head_points_at->name,
"refs/heads/");
update_ref(reflog_msg.buf, "HEAD",
our_head_points_at->old_sha1,
NULL, 0, DIE_ON_ERR);
...
afaik from gdb HEAD ended up being a symlink to "" ref or so.
