If you guys can remind me when Fedora gets a version very close to the
next ESR, I can go look at their build logs to see what we need and get
started earlier.
As a person who is planning and overseeing the whole rebase of Thunderbird and Firefox in RHEL, I can make a note to let you know what toolsets we will start to require when we will work on next year's FF/TB rebase.
