Does $release-updates includes $release-security?

  • 772

from the man page for sources.list:

The format for a sources.list entry using the deb and deb-src types is:
    deb [ options ] uri suite [component1] [component2] [...]

from https://help.ubuntu.com/community/Repositories, suite can be any of those value:

$release: Don’t touch it, I like consistency, even with my bugs.

$release-security: I’ll accept patches to existing versions (and very rare version upgrades if absolutely necessary) in the process of keeping my system secure.

$release-updates: Okay, some bugs are worth fixing, and I trust you this much (holds up two fingers like Maxwell Smart).

$release-backports: I have something akin to technology ADHD, needing the latest of everything I can possibly get, but I can’t handle running the development branch.

$devel: I can take it. Seriously. If you break my X, I shall become more powerful than you could possibly imagine. I’ll file and maybe even fix the bugs and I’ll do it even if power management is not so much ‘managed’ as vomited all over the wall. Come get some.

My question is:

  • Is every update included in the $release-security included in the $release-updates?

further more:

  • Is every update included in the $release-updates included in the $release-backports?
  • Is every update included in the $release-backports included in the $devel?

    At any given moment of time: No. (x3)

    The channels are mutually exclusive. The security channels are fixes of the highest importance. The updates channels are for fixes that couldn't reach security, but still fixes of some sort. backports may contain bug fixes, but that is not their primary aim, and so it should not have anything in common with security or updates.

    All packages go through proposed for testing before they reach security, updates or backports. For example gnutls-2.12.23-12ubuntu2.1 reached proposed in June, and is now in security.
