I think it might be nice if those two aspects could be isolated somehow.
This could also reduce the size of some build chroots and the set of packages
any boot-strap code has to handle specially[1]. With all the essential
stuff only needed for a full system to boot, those are larger than they
needed to be.
I think
e2fsprogs
login
mount
sysvinit
sysvinit-utils
util-linux
and their dependencies (passwd, initscripts, the whole pam stack)
are mostly not needed in that set[2].
(Util-linux might have one or two programs one might want to move
to another package then, and something for update-rc.d needs to be
done).
How about giving the old meaning of Essential to packages being
Essential: yes and Priority: required and allowing a new state
Essential: yes and Priority: important that means a package manager
has to make sure its functionality is kept[3] but everything not
having a Dependency is still supposed to work (do build chroots,
embedded stuff or other things can do without them).
Bernhard R. Link
[1] bootstrap code essentiall needs to unpack those and all their
dependencies manually and then call dpkg to do that again...
[2] At least I often build some of my packages in chroots not having
any of those.
[3] Though in my eyes "not removed" might suffice. Being able to login
always but having no guarantee a sshd is still running and working or
that it is still bootable gives not much in my eyes.
