In todays 2.6 git repo, I see the following:

$ fsck-cache
expect dangling commits - potential heads - due to lack of head information
dangling commit 897f5ab2cd733a77a2279268262919caa8154b9d
dangling tree c39ae07f393806ccf406ef966e9a15afc43cc36a

The dangling commit is the current head - that's fine.  However,
what's this dangling tree?

It appears to have come in from Linus' tree on kernel.org this morning.

(above from cogito 0.8)

As an additional note, the ID does not correspond with any tags or
heads:

Those are tag objects.

$ git-cat-file tag 5dc01c595e6c6ec9ccda4f6f69c131c0dd945f8c | head -3
object c39ae07f393806ccf406ef966e9a15afc43cc36a

See the message on 'nightly kernel builds' - you are seeing 2.6.11 probably.

That's the 2.6.11 tree, which I added to have a previous real release to 
diff against.

Yes. You can make (my) fsck shut up with something like

	refs=.git/refs/*/*
	git-fsck-cache $refs

but that assumes that cogito has been updated to the newer fsck that 
understands to follow tags (not just parse them, but also add the "tag 
refers to object xxx" info to its internal tree of trust). I don't think 
that has happened yet.

In the meantime, just ignore it.
