I'm repairing a system for a friend with a FAT filesystem
problem.
There is a directory cycle, so that for example:
rm -rf directory_with_cycle
doesn't work, because rm encounters and endless succession
of subdirectories.
The directory content is not important, however I'd be
interested in knowing some FAT references that could help
me to eliminate the loop and remove the directory.
Regards,

A symlink loop? But FAT doesn't support symlinks.

I would run the fsck.vfat ( dosfstools package) on the unmounted partition.

I tried that; fsck.vfat gets stuck in a loop as it descends
into a subdirectory that contains its own ancestor.
Thanks anyway!

I thought fsck was a bit based integrity checker and didn't care about directories?... and how do you know what directory fsck is on anyway?
Either way, rsync the disk (I think there's a follow symlink option). Copy the first 454 bites of the disk. Reformat the disk, copy the data back, dd the mbr back.

The same warning repeated endlessly

Rsync *does* allow one to exclude directories from the copy.
So that would work.
However Windows system partitions always have special
wrinkles... A fresh install might help.
I think I'm about done with this job. I've got Windows
booting, and I've got Puppy linux running as an alternative.
Thanks for your suggestions

Show us. Include *everything*. (Snip after 5 lines of repetition.)

Okay, I get that a responsibility of posting for help here
is also to include enough info for all to study.
Thanks for your kind offer, however I no longer have the computer
to play with. I'll experiment with virtualization next,
if I can get that to work.

You call the Doctor saying nothing but "I have a cough. Cure me
now!" and expect him to do what?

Hi Doctor Johnson,
At least half of the time, the *attempt* to explain
to the doctor cures the problem.
Several times I've spent more than an hour writing
to the list, and then resolving the problem
through the exercise of writing.
(I don't usually trouble the list unless I'm feeling
especially boastful.)
In this case, I ran out of time and returned the
hardware.
I don't appear to get the same errors on the dd'd and
mounted partition copy that I recall on the original
hardware.
There could have been some error on my part.
Some errors remain mysterious.
Thank you for explaining list etiquette.
Let it be known that I contribute to this list as well as
asking for help. I attempt to remain courteous, including
providing sufficient information.
Good day to you, Dr. btw, we are all doctors and all
patients here!
Have a tofu flavored banana bar and chill :-)
