s6-rc/src/repo/s6rc_repo_setuptodate.c, branch v0.8.0.2The skarnet.org service managerhttps://git.skarnet.org/cgit/s6-rc/atom/src/repo/s6rc_repo_setuptodate.c?h=v0.8.0.22026-10-17T04:10:16Z Third part of the format-upgrade inclusion: add support in s6-rc-set-install2026-10-17T04:10:16ZLaurent Bercotska-skaware@skarnet.org2026-10-17T04:10:16Zurn:sha1:6ada80ed7e45ed630e4d9877a9b11e2dfddb4758
Now that everything is in place, we go for the main thing: add
snapshot support to s6-rc-set install. The workflow is:
- check the major version of the old db against the current s6-rc
- if the old db is up to date, nothing changes
- otherwise:
+ find the snapshot corresponding to the old db
+ compile it
+ copy the snapshot db to the bootdir
+ call s6-rc-format-upgrade on it
+ atomically switch the bootdb to it. At this point the snapshot
is the new bootdb: same as the old db, but with the correct major version.
+ unconditionally remove the old db
+ and now we can perform the regular s6-rc-update with the
wanted set, since they have the same major.
We also add --no-snapshot options to s6-rc-set-commit and
s6-rc-set-install, and propagate them in the supporting functions,
so users can manually skip all this bloat (and this is important
for the initial install).
All that remains is cleaning up obsolete snapshots. This will
probably go at the end of s6-rc-set-install as well.
Second part of the format-upgrade support: ensure snapshots are there2026-10-15T05:17:26ZLaurent Bercotska-skaware@skarnet.org2026-10-15T05:17:26Zurn:sha1:91a0655557e707977f583b2142bda898ee599fd8
We don't want to install compiled dbs without having a snapshot of
their source set, so whenever we test that the compiled db is up to
date, we also test that a snapshot is present. This is important
because we will auto-cleanup unused snapshots after installation.
But this day is not today, so screw it.

s6-rc-set-install is undergoing changes, it might not work
properly. The rest is coming this week.
