Adam: Thanks so much for the thorough bug report!
>From looking at the code, I also cannot see how "--remove-all-files" could possibly respect the "EXCLUDE_FSTYPES" option. This does not agree with the documentation at all. Note that deluser.conf(5) currently has this to say... EXCLUDE_FSTYPES A regular expression which describes all file systems which should be excluded when looking for files of a user to be deleted. Defaults to "(proc|sysfs|usbfs|devpts|tmpfs|afs)". This seems like a pretty clear contract with the user to skip deletion of data residing on file systems of these types. I will mark this bug as confirmed so that it can be handled in a future release. Thanks again! -- Jason Franklin
