# By default, Slackware builds dhcpcd with privilege separation, which improves
# security by ensuring that any security vulnerabilies such as buffer overflows
# or shell metacharacter insertion would gain access to an unprivileged user
# (the dhcpcd user) rather than the root user. However, this creates issues
# when using dhcpcd with NetworkManager. With privilege separation enabled,
# the network won't return properly after suspend/resume.
#
# If you use dhcpcd with NetworkManager and this functionality is important to
# you, rebuild dhcpcd with this command:

# PRIVSEP=no ./dhcpcd.SlackBuild
