# Description: Now that TCP/IP is configured, mount the NFS file
# systems in /etc/fstab if needed. If possible,
# start the portmapper before mounting (this is needed for
# Linux 2.1.x and up).
#
# Also mounts SMB filesystems now, so the name of
# this script is getting increasingly inaccurate.
# Skip the mountnfs hook when being triggered by the networking SysV init
# script and instead use the systemd built-in mechanisms to mount remote
# file systems.
# This avoids a deadlock caused by the rpcbind SysV init script depending
# on $network and the $network LSB facility being provided by the networking
# SysV init script.
