Great info, thanks. This is an 1.5+ year old coreutils but I couldn't
reproduce the problem on Linux with the same (newer and older) coreutils
versions.
If the latest, version 6.12, coreutiles doesn't work either then please
submit a bug report to them, noting that Solaris rm works and coreutils too
on Linux.
Thanks,
