This example shows the default "rm" (PATH not shown) failing to remove a
directory tree, but succeeding on the second attempt.

This example show GNU coreutils rm v6.12 failing to remove a directory
tree; even though the exit status is 0, not all files are deleted. This
is a bug.
@osol /ntfs: /usr/gnu/bin/mkdir -p t/t/t/t/t/t/t/t/t/t//t/t///t//t/t/t/
@osol /ntfs: /usr/bin/rm -rf t
@osol /ntfs: ls t
ls: cannot access t: No such file or directory
This example shows /usr/bin/rm successfully deleting a directory tree.
To determine whether this is a bug with GNU rm or interactions between
your kernel and the NTFS filesystem, it's necessary to trace the system
calls and their return values - hopefully your solaris system has truss
installed, in which case you could try to repeat the failing commands
given above like so:
$ truss -o rm-trace.txt /path/to/rm -r t
If you are able to interpret the output of truss, please try to identify
where GNU rm and solaris rm differ in their system calls, specifically
which files are removed with unlink(2). If not, then please just attach
the truss output, ideally compressed.
Cheers,
Phil
