Two things :
1) I used the following on the host (you noted I do not need
systemd-networkd on the host)
# dnf install systemd-networkd
==>
No match for argument: systemd-networkd
Error: Unable to find a match: systemd-networkd
2) To create the container (feedback welcome) I used :
//
export RELVER=30
dnf -y --nogpg --releasever=${RELVER} --installroot=/var/lib/machines/nh286
install systemd systemd-networkd passwd dnf vim-minimal iputils iproute
procps-ng vim-enhanced
==> ...
No match for argument: systemd-networkd
Error: Unable to find a match: systemd-networkd
NOTE: the dnf command I have used previously for other container
builds/creation on other hosts
