 ==== reproducible Arch Linux
 
+* cleanup below…
+* build in /srv/workspace instead of /tmp
+* do 2nd build on pb4
+* < Foxboron> the multilib builds are failing because multilib-devel isn't installed. Thats the base-devel for multilib packages.
+** -> disable multilib for now?
+* extract .BUILDINFO files and submit them to buildinfo.debian.net^wbuildinfo.reproducible-builds.org
+
 * https://bugs.archlinux.org/task/50086 - pacman doesnt create reproducible packages yet
 * describe archlinux setup…!
 * maintenance job:
