# The Hurd, the Linux kernel, the FreeBSD kernel version 2.2 and later,
|
|
# Cygwin, and mingw never let anyone (even root) unlink directories.

# If anyone knows of another system for which unlink can never

# remove a directory, please report it to <bug-coreutils@gnu.org>.
|
|
# Unfortunately this is difficult to test for, since it requires root access
|
|
# and might create garbage in the file system,
|
|
# so the code below simply relies on the kernel name and version number.
