Hi,

There are very little dependencies of NetworkManager to systemd. Note
that the src/systemd directory contains a self-contained copy of
systemd sources. That is, you don't need an systemd dependency for
those.

Regarding session management, you'd only have to patch
https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/src/nm-session-monitor.c?id=fa15543179aa8ca8e082267121e7df4a131bf642
That seems doable.
