Hello.
There is a big question with torture me for awhile. Why some purely
declarative operations are performed by non-standard postinst scripts?
I've checked few well-established packages (openssh, nginx, systemd,
dbus, cups, etc) - each of them have slightly different code for such
operations.
Example of such operations:
- adding and removing users
- changing permissions and mode for files
- creating symlinks
- reloading/restarting daemons
etc.
Is there any kown reason why such operations are forced to be 'write it
again and again' style, or it's just a historical luggage?
