 * Creating start-up services for mac build slaves
   + guilhem: missing some context
   + cloph: at the moment building LibO on mac requires a graphical login
   + cloph: on windows there is something to automatically start a graphical
     login, but unsure how to do for macs
   + currently macs are managed manually, need to connect manually and start a
     graphical login on reboot etc
   + minor convenience?
 * TGClean: Delete-Bot for old Telegram messages (esp. the LibreOffice-channel,
   but also others)
   + tg groups/bots aren't managed by the infra team at large, it's done by a
     so-called botfather / single group admin (cloph atm)
   + EV: do we agree that we need to clean up the history?
     cloph: depends on the channel, but just preventing newly joined users from
     accessing the history would already solve most concerns
 * Old TLS profiles
   + Currently all boxes running Buster use Mozilla's "intermediate" TLS
     profiles (no TLS <1.2, no CBC/RC4, etc), in practice all browsers ≥12
     years old should work,
   + Most likely not an issue for services accessed from a normal
     browser (website, wiki, ask, etc), at least noone complained so far
   + Might be problematic for systems accessed from LibO: update check (0.02%
     excluded, 7k out of 50M) and crashreport (0.03% excluded, 95 out of 300k)
     - cloph: that's just noise, so few that it's not relevant enough for QA
       anyway we can afford rejecting these handshakes
     - [rdm#3187] more problematic if that's Xisco's system (he said he'll upgrade)
     - possible workaround:
 * Allow attachments on public mailing lists
   + on a per-mailing list
   + cloph: not worth discussing here, we can do a test and disable
     pymime on some lists to give it a try and see if people complain
   + AI guilhem, do it on all lists with ≤150 subscribers for now
 * Hypervisor upgrade
   + charly upgraded to Buster 3 weeks ago
   + backported libvirtd 6.0 (to access better guest info, FS usage,
     kernel version, OS, etc.)
   + AI guilhem need to make fancy grafana dashboards and alert rules
     (FS filling up, old kernel running, etc.)
   + AI guilhem upgrade other hypervisors starting with dauntless (to
     be announce on the website+dev list)
   + crashtest is now a metal host, no longer living on charly
   + charly is now rolling thumbs, we can rebalance guests to free up
 * Streamline firewall on the Debian ≥10 baseline? (nftables, firewalld)
   + baseline uses shorewall right now
   + v4/v6 aren't unified by default, need to symlink but care should be taken
     when filtering by subnets
   + iptables scripts are harder to read and write atomically
   + kernel nf subsystem use nftables modules now, xtables is legacy
   + guilhem: suggests to just ship plain nftables, easier to read/write and
     apply atomically
    . config has a macro language and ipsets are supported natively
    . native v4/v6 consolidation
   + EV: how complicated are the shorewall rules anyway
    . we don't have many rules on top of the defaults, just opening the
      relevant ports and enabling forwarding for intranet
      - allowing SSH just is: 
        SSH(ACCEPT)     all             $FW
   + guilhem to write a salt state as a PoC and deploy it on some guests as a
 * Pending AI:
   + guilhem Move infra testbed ( )
     to Gerrit and make the salt repo world-readable
   + before going public: Use `git filter-branch` to remove certs and privkeys
     that were once uploaded there
     . won't be fast-forward so disruption for local clones, but just a one-off
 * Next call: Mon May 18 16:30:00 UTC 2020
