Probably not, but the short and long hostname as returned
by the hostname command (which can differ from what’s in
the file). [Update: hostname -f does DNS lookups, so we
take whatever hostname without an argument returns, which
is the node name as known to the kernel, and if it contains
a period, also add the short(ened) form.]
In the long term, however, adding more and more tricks for
packages doing network stuff during build is not the best
way forward, I’d definitely patch them, so they connect to
localhost only. But this one is easy enough, I think, so
let’s do that. (Attached.)
