My BSP doesn't have the directory, projectroot/usr/lib/systemd/network/

ptxdist projectroot is providing eth0.network, that has the correct
permissions.
jringle@dev-atl-bamb01:/usr/local/lib/ptxdist-2019.01.0_GP/projectroot/usr/lib/systemd/network$
ll
total 12
drwxr-xr-x 2 root root 4096 Feb 12 05:18 ./
drwxr-xr-x 4 root root 4096 Feb 12 05:18 ../
-rw-r--r-- 1 root root   70 Feb 12 05:18 eth0.network

The 80-container-*.network files that have the wrong permissions are coming
from the install_tree, not the install_alternative_tree, which is provided
by the systemd itself:
jringle@dev-atl-bamb01:/srv/gpec-build/rootfs/platform-ec1c/packages/temp/data/usr/lib/systemd/network$
ll
total 28
drwxr-xr-x 2 jringle domain^users 4096 Jan  1 00:00 ./


drwxr-xr-x 5 jringle domain^users 4096 Jan  1 00:00 ../


-rw-r----- 1 jringle domain^users  645 Jan  1 00:00
80-container-host0.network


-rw-r----- 1 jringle domain^users  718 Jan  1 00:00
80-container-ve.network


-rw-r----- 1 jringle domain^users  704 Jan  1 00:00
80-container-vz.network


-rw-r--r-- 1 jringle domain^users  412 Jan  1 00:00 99-default.link


-rw-r--r-- 1 jringle domain^users   70 Jan  1 00:00 eth0.network
