When I try to enter the cvs gnus that I upped this afternoon, I get:

Signaling: (file-error "Creating directory" "file exists" "/home/lconrad/Mail/world/old")
  make-directory-internal("/home/lconrad/Mail/world/old")

I don't get this, `gnus-make-directory' should only create the
directory if it does not already exist:

(defun gnus-make-directory (directory)
  "Make DIRECTORY (and all its parents) if it doesn't exist."
  (require 'nnmail)
  (let ((file-name-coding-system nnmail-pathname-coding-system))
    (when (and directory
	       (not (file-exists-p directory)))
      (make-directory directory t)))
  t)

Is there something wrong with `file-exists-p' in your setup?  NFS?
Does `(file-exists-p "/home/lconrad/Mail/world/old/")' really evaluate
to nil?  The directory exists, right?

Maybe `file-directory-p' should be used instead?

No.  I was going to post a followup.  That directory is (was) a link to a
directory that used to exist before I rearranged all my partitions.
It exists now, and I can use the CVS gnus.  Which is good because it
does several good things that the latest ognus release doesn't.  But
I'm probably not the only person in the world who rearranges
partitions and doesn't fix all the links to the old partitions.  And
gnus never complained about this before today.

So the error message was correct?

Hm, what would Gnus do other than to complain?  As I see it, the
directory where a nnml group lives must exist in order to write things
into it.  If it doesn't exist, Gnus tries to create it.  I suspect the
reason you haven't received the error message before is that you
didn't write to the group (i.e. deleted or inserted articles).  Would
that be right?

I don't think there's a bug here.

The error message may have been correct, but gnus should have
recovered from it and let me in anyway.  My complaint was that I
couldn't run gnus at all.

    Simon> Hm, what would Gnus do other than to complain?  

Let me read my other groups.

This isn't a group that mail gets sorted into; it's the archive group
that mail from another group gets expired into.  So I don't see why
gnus should be trying to write to it on entry.

    Simon> I don't think there's a bug here.

I disagree; no matter what damn fool thing the user has done she
should still be able to get into gnus.

I see.  Please try attached patch, it will ask you if Gnus should
continue even if the nnml directory is FUBAR.

Well, it tries to create the .marks file to make it possible to
e.g. backup the nnml server independently of .newsrc.eld.  The group
is only written to once; when you don't have a .marks file and nnml is
bootstrapping it for you.
