Bug#824991: override: init:metapackages/important

[Ansgar Burchardt]

Package: ftp.debian.org
Severity: normal

As discussed in [1] I would like to make it possible for minimal
systems (mostly buildd chroots and application containers like Docker)
to not have to install an init system.

For this the "Essential: yes" field is moved from "init" to
"init-system-helpers" (to provide invoke-rc.d/update-rc.d). I would
also like to downgrade the priority of "init" from required to
important. With the priority change, debootstrap should no longer
install a full init system in the "minbase" and "buildd" variants.

On the d-i side, I hope this doesn't break anything as debootstrap's
default variant should not be affected by these changes, unless d-i
can also install a "minbase" variant?

And just for the record: a system with no "init" should have a
"policy-rc.d" policy that rejects all actions, but this is already the
case for chroots.
