Comment 19 for bug 1848923

@Christian: Debian still needs/wants to support sysvinit. Of course init.d scripts ought to create cache directories too (like munin, mopidy, and others already do, but probably not all of them), but that will be a bit more work. FHS applies to SysV init as well, so the same reasoning still holds. Also, some postinsts seem to do legitimate work, like fontconfig which also creates an initial font cache.

If you want to start an MBF, it first needs some initial discussion, or at least announcement, on debian-devel@ [1]. And then it needs checking which packages actually have that problem, as I don't think it's actually *that* many -- two dozens tops? But in general I think this is a nice goal for sure. (For the record, we have not detected any problems related to this in the Cockpit test suite on any Debian or Ubuntu image, except for pollinate)

The "/var/cache/ should be removable" reference is [2], it was already in comment #9:
