I think that is usually a valid approach, as I understand it at present,
yeah. The only thing likely to set the transient hostname is DHCP, and
if you explicitly specify a static hostname, DHCP will not override it;
AIUI, all the Fedora networking bits are configured to only set the
hostname from DHCP if there is no explicitly user-configured hostname.

Note, one thing I found screwing with hostnamectl's story of how
hostname setting works is dracut: if you set /etc/hostname once and then
wiped it you might think you've un-set the static hostname, but your
initramfs likely contains a copy, and it looks like dracut sets the
hostname specified in its copy of /etc/hostname during early boot.

(I was trying to get my systems' hostnames set via dhcp in a reliable
way; this seems to be extremely difficult, and for now I've given up and
am just brute forcing the 'correct' values. The closest I got was that
each system would boot with 'hostname' returning 'machine' and 'hostname
-f' returning 'hostname.happyassassin.net', but this apparently isn't
enough for freeipa, which expects 'hostname' to return
'hostname.happyassassin.net' . This hostname stuff is so complicated I
don't even know whether I should claim that's a bug on freeipa's part -
that anything which requires an FQDN should do the syscall equivalent of
'hostname -f' - or not.)
