Hi,
I also frequently encounter these errors.
I think they are caused by me copying from an ancient local clone, one
that still has historic account of when hadrian used to live in its own
submodule.
Recently, the hadrian system vendored Cabal into hadrian/vendored/Cabal,
but the root repository had still listed a submodule at
.git/modules/hadrian, explaining the error.
Indeed, just removing the ancient .git/modules/hadrian is the solution.
Note that the vendored submodule means you cannot easily check out a
branch from ... 5 years (?) ago, because then you will get the reverse
error.
Fresh clones should not be affected.
Cheers,
Sebastian

Betreff Re: Can't initialise vendored submodule
Thanks Matthew, this helped me find the solution.
Which, is turn out, was simply to remove the old directory:
$ rm -rf .git/modules/hadrian/
It's not removed by `git submodule desync` or any command that I could
find (though, now that I think about it, I didn't try to garbage
collect the repo, so maybe?). But it's sound to just delete, as far as
I can tell: it's just a cache.

This goes to show that I was at least right when saying that submodules
are wonky :D .

It seems you might have a some very old configuration from when

things along?
The usage of submodules in `hadrian/vendored` is a standard usage.
Cheers,
Matt

Dear all,
I'm currently unable to build GHC's master branch as some of the
submodules (presumably used by Hadrian) are making git pretty
unhappy (I've used various variants of the command below, in a
cleaned repository):
```console
$ git submodule update --init
error: submodule git dir

```
Please advise on how to get unblocked.
And, if I'm allowed to conclude with a plea: please be careful not
to abuse Git's submodule system, it's wonky enough when used simply.
