Subject: fix(network-manager): only run NetworkManager if rd.neednet=1
X-Git-Tag: 054~121
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ac0e8f7dcc81432311906c3fca0d4211f6a2f68c;p=thirdparty%2Fdracut.git

fix(network-manager): only run NetworkManager if rd.neednet=1

Don't run the new systemd unit (nm-run.service) if rd.neednet=1
isn't set. nm-initrd-generator will generate configuration even
without rd.neednet=1 so determining if we should start based on
just if connection profiles exist isn't enough. We need some other
indicator. In this case we lay down a /run/NetworkManager/initrd/neednet
if rd.neednet=1, which is used by nm-run.service to determine the
need to run.
