# Also remove dependency on statd.service.

# 'portmap.service' is removed from Requires= and After= lines.

# We don't need new dependencies for rpcbind, because this is socket
# activated (if socket unit is enabled) and the service units order
# after sockets.target via DefaultDependencies.
#
# Additionally, for nfsd.serviced, we remove the '--descriptors 64' limit, which
# is to low for the mountd of nfs-utils 2.3 when serving  ipv4,ipv6 and
# named sockets.

# This implies, we can't just push the changes around from the distmaster,
