I would really like to have those pkg's and the programm (pkg) separated, for example:

For the system the program "pkgs" ("s" for system) can write to /bin /sbin etc, and can only install/remove .pkgs (system packages)

For port's (can only write to /usr/local) pkg and .pkg

With that we can have the same separation as we have now, for me that's a big plus on the BSD side of things. BTW Windows, Android and MACOS have some kind of that separation too.

pkg delete -af removes all "port" pkg's

pkgs delete (has no option -a but options like IDS from freebsd-update where every installable file IN the package (a *.pkgs) has a checksum instead just the pkg itself)

Drivers/Firmware will then have to move to pkgs, also we can have different groups for maintaining the system and port (root/wheel for pkgs and operator for pkg)

Also packaging error's in port packages cannot damage your system.
