What should postrm purge actually do?
Is it written down anywhere what postrm purge is supposed to do?
Presumably remove some set of files, but what criteria should be used to
choose which?
The policy document is not much help; s6.8 says when it is called, but
not what it actually needs to do. I can't find more detail, though of
course I may have missed it.
Things I think it should remove:
- generated configuration files
Things I'm uncertain about, but that wouldn't be missed:
- infrastructural stuff (lockfiles, sockets, etc)
- files containing cached data
Things I'm uncertain about, that someone might actually miss:
- log files
- data accumulated from users
Configuration files might be missed too, so obviously --purge isn't
intended to be nondestructive, the question is how destructive is it
supposed to be and to what extent is it responsible for tidying up.
