Yeah, in Ubuntu we kind of cheat. The installer is using sysconfig
stuff, but at the end of the install uses chzdev to take a dump of the
running configuration and store that on disk. This way all installed
systems only use chzdev/lszdev.
You can install and use ubuntu package, and chzdev/lszdev configs are
not conflicting with existing stuff as they simply generate udev rules
that one places in /etc/udev/rules.d/ dir.
I was late on many things for stretch =/
Ideally I was hoping to have full chzdev support in d-i, such that one
can preseed any devices, with any of the supported args (e.g. to be
able to install the system with e.g. bridge_role=primary et al)
