# The original unscd would crash, because it is not allowed to create its
# legacy socket at /var/run/.nscd_socket.
# This socket is only required for very old glibc versions, but removing it
# is currently non-trivial, so we just move it somewhere, where it is
# allowed to be created. A patch has been submitted upstream to make this
# hack unnecessary.
# Also change /var/run to /run, since we shouldn't be using /var/run
# anymore.
# See also: http://lists.busybox.net/pipermail/busybox/2021-June/088866.html
