>> Topics proposals:
>>     - multiarch CI status? (Scheduled)
>>     - cross-SIG CI ? (Scheduled)
>>     - workflow/process for deprecating SIG contents. +2 (Scheduled)
>>     - allow SIGs to have separate accounts for build bots. +1 (Scheduled)

>>    - Building embargoed content
>>
>> Notes:
>>
>> Introductions
>>
>> Multiarch CI (Haikel)
>> - no automated ci for all platforms
>> - if you're using CI, please subscribe to ci-user-list
>> - ppc64(le) machines are available, but request is manual right now.
>> - aarch64 boxes are small, community donated. Power-capacity is way bigger
>> - more detail on the multiarch page in the wiki (not able to find it
>> through https://wiki.centos.org/QaWiki/CI/Duffy )
>> - https://wiki.centos.org/QaWiki/CI/Multiarch
>> - use cico client for interaction wih CI system
>> - cicoclient multiarch support has been merged =>
>> https://github.com/CentOS/python-cicoclient/pull/14
>> - suggestion to use zuul instead of jenkins for managing job queues
>> - AI on alphacc: add template for requesting sync to buildlogs to mention
>> architectures etc...
>>
>> Cross sig ci (Haikel)
>> - sig start depending on other SIGs, (multiple examples given)
>> - question on how to test pre-released packages
>> - to test against extras, SIG should provide tests to t_functional from
>> CentOS QA. Wiki page is located at https://wiki.centos.org/QaWiki
>> /AutomatedTests/WritingTests/t_functional. git is located at
>> https://github.com/CentOS/sig-core-t_functional. Results are to be found
>> at https://ci.centos.org/ (search for "pretest" for results before
>> package release and for "t_functional" for daily tests)
>> - define a matrix for SIGs depending on each other trigger tests - start
>> email thread on ci-users list, create dependency graph from centos-release-*
>> - CI and CBS meeting on Mondays on #centos-devel
>> - CICO statistics are partially available through CentOS Zabbix instance
>>
>>
>> Workflow/process for deprecating SIG contents (mrunge)
>> - Historically we do not delete content ever. But we can move it to the
>> archive/vault, and stop distributing it by default
>> - reasons to remove packages from the repository (move to vault.c.o):
>>     - newer package in the (base) release
>>     - dependency not needed any more from a newer release of your package
>>     - end of life for versions (centos-release-gluster with per-version
>> repositories)
>> - need a workflow for deprecating/removing a package
>> - SIGs are for experimentation - it's not for the distro to tell them how
>> to run their process.
>> - single package removal by untagging - also needs update to KB's sync
>> script
>> - whole repository removal by filing a bug,
>>
>>
>> Allow SIGs to have separate accounts for build bots
>>  - separate user accounts from "bot" accounts for security reasons
>>  - [proposal] have an email alias (not list) per sig for the bots, like
>> sig-<bla>@centos.org pointing to the SIG's chair
>>  - [proposal] SIG chair must request or approve email alias requests/ ACO
>> account creation sent to CentOS Board chairman
>>
>> Package Signing
>> - SIG chairs should request feedback/insight into the package signing
>> process --> KB
>> - sometimes, there is a delay in package signing/sync to
>> mirror.centos.org
>> - have keys been generated securely (known bugs in package versions that
>> make less secure keys?)
>>
>>
>>
>> Sig request for sig specific git
>> sigs would like to use centpkg / lookaside, build direct through git to
>> koji
>> authentication requirements to accounts.centos.org
>> Fabian to evaluate git solutions and report back to sig chairs.
>> mrunge has volunteered to be the "guinea pig" of the new system
>>
>>
>> Manage CBS multiarch at minor release ; quicker access to packages than
>> distribution does, delegate more (i686?), etc...
>> - pre-CR buildroot for koji?
>> - does any SIG build against c7/i686? No, probably not
>> - For 7.4 building all the Alt-Arches took additional time, thus delaying
>> the release. There is work being done to improve this for future releases
>> - is it possible to spread the load for contributors for building on alt
>> arches?
>>
>> Other topics
>>
>> * Building embargoed patches
>> - current practise: build as soon as the embargo is lifted - wait for
>> sign+push to mirror
>> - improvements possible for signing packages faster

Should I take lack of answer like a no?
