Steps to reproduce:
run mach bootstrap on arch linux
KeyError: u'VERSION_ID' at https://searchfox.org/mozilla-central/source/python/mozboot/mozboot/bootstrap.py#260
VERSION_ID is an optional field and arch doesn't supply it.
Script should run successfully.
Looks like bug 1581921 introduced this
Uh oh, sorry about that!
Do you want to try fixing this? If not, I can try, but I don't have Arch sitting around.
Some fields of /etc/os-release are optional, so do not throw KeyError's when they're missing.
