I'm looking at unitfile -> sysvinit conversion for a remaster project of mine.
The scope is narrow in my case, but I'm curious if it could scale enough to be
useful. Like... convert the bulk of standard service management and
automatically detect weird edge cases for manual review... (e.g. dumping them to
file as "interesting, weird, please check me..."). It would likely be a net gain
over trying to get raw manpower to handle every single package always.

Maybe take this an inch at a time so it doesn't metastatize. Enough to be useful
but no more (especially not enough to become its own stand-alone PITA).
