support for build-base
Metadata
Current evaluation
Build-base support was implemented in Snapcraft commit 5dea8acba; Launchpad stable revision r19009 added remote support, and eligible snap types were confirmed working.
Resolution: closed resolved
Reason: Snapcraft commit 5dea8acba added build-base support, while Launchpad stable r19009 added the required remote-build support. The closing confirmation states that Snapcraft supports build-base for the applicable snap types.

Issue body
A fully static snap, such as a base can be allowed to build using a different base to create the base.
Some valid scenarios exist for such feature:
base: bare
and
type: kernel
or
type: base
Support in launchpad for build-base is also required (https://bazaar.launchpad.net/+branch/launchpad/view/head:/lib/lp/snappy/model/snap.py#L620)

| #2700 schema: build-base support for the kernel type | snapcraft | merged | Merged in #2700 as c360ffab6, adding build-base schema support for kernel snaps while allowing them to omit base until hooks exist. | |
| #1819290 Support for "base: core" | snapcraft (launchpad) | closed | Implemented by merged snapcore/snapcraft#2499 (commit e1cc2b91c), adding 'base: core' support in snapcraft.yaml and stripping it from generated snap.yaml; Launchpad base config updated by cjwatson. | |
| #36 project: support build-base and allow 'bare' bases | rockcraft | merged | Merged in #36 as commit 5a27aca4, adding build-base, bare bases, and Ubuntu 22.04 support; follow-up commit d1a5f04c corrected a bare-base rebuild bug. | |
