To create a place to collect what you & Google teach me over time, I
will go ahead and mention:

Often I find if I create an initially zero + `mkudffs` disk of 1 GiB,
the Philips udf verifier udf_test complains as follows.

...
    309 read block
EFE  file type DIR    name: "lost+found"
EFE  28  icbtag error: parentICBLocation: (34,0),
- recommended: (0,0) for strategy type 4.

- or to a higher parent in the directory hierarchy.

Courtesy the linux-fsdevel "editable udf metadata" thread, specifically:
http://marc.theaimsgroup.com/?l=linux-fsdevel&m=106677828430258
we now have this same error printed in Linux.

In the example tty log below I override the --udfrev 0x0201 default of
mkudffs, and still I get much the same error.

Kindly offline, in reply to this thread titled "udf folders pointing to
self and above", I received the hint:

        use cvs udftools

Anybody here already have a clue how I can click thru that link?

Apparently I'm testing the wrong code?

Didn't kernelnewbies.org once contain a cvs tutorial?  Revisiting now,
all I find is an rtfm link? ...

I had reported that the udf mkfs fails the udf fsck.

By "the udf mkfs" I mean the udftools-1.0.0b2/mkudffs/mkudffs that
`make` creates from:

http://sourceforge.net/projects/linux-udf/
http://sourceforge.net/project/showfiles.php?group_id=295&release_id=74270
...

By "the udf fsck" I mean the udfct_1.0r2/src/udf_tester/udf_test that
`make` creates from:

http://www.extra.research.philips.com/udf/download/udfct_1_0r2.tar.gz

kernelnewbies thread "Re: use cvs udftools means what" has an answer:

http://marc.theaimsgroup.com/?l=kernelnewbies&m=106686957020891

To get the mkudffs we want people to test, possibly all we have left to
discover is how to correct the spelling of the line:

export CVSROOT=:pserver:anonymous@www.diabetikware.org:/home/cvs

P.S. Sorry the first post of this thread does not have two blanks past
the Re: in "Re:  Fwd: udf folders pointing to self and above".

Now I am iterating over firewalls.

Failure looks like:

$ export
CVSROOT=:pserver:anonymous@cvs.sourceforge.net:/cvsroot/linux-udf
$ cvs login
Logging in to
:pserver:anonymous@cvs.sourceforge.net:2401/cvsroot/linux-udf
CVS password:
cvs [login aborted]: connect to cvs.sourceforge.net(66.35.250.207):2401
failed: Connection refused
$

P.S.

I see no hits at:
http://groups.google.com/groups?q=CVSROOT+cvsroot+linux-udf

Instead I got to this guess by combining kernelnewbies "use cvs udftools
means what" with the web trail:

http://sourceforge.net/projects/linux-udf/

CVS
http://sourceforge.net/cvs/?group_id=295

Basic Introduction to CVS and SourceForge.net (SF.net) Project CVS Services
http://sourceforge.net/docman/display_doc.php?docid=14033&group_id=1

Re: Fwd: udf folders pointing to self and above

[Pat LaVarre]

Solved!  Indeed, solved by "use cvs udftools", precisely as hinted.

Thank you all.

P.S. A tty log of the contrast follows ...

Versus the 2002 Feb 9 1.0.0b2 udftools of sourceforge, I yield 2643 
lines of diff -ur if I try:
