I still believe we should stick to a generic hostname by default,

order to drop the redhatism that "localdomain" is), and make the IPA
client-side enrollment code automatically update to a more "unique"
hostname if the hostname is found to be unset or be "localhost".

I am also pretty sure that DHCP clients should suppress sending local
hostname information if the local hostname is unset or "localhost".

Given the text of RFC6761 [https://tools.ietf.org/html/rfc6761#section-6.3], something like "fedora-XXXXXX.localhost" would also be an option, if we absolutely needed a domain component. ("localdomain." seems like a not-invisible number of root TLD lookups at http://stats.dns.icann.org/hedgehog/). But a simple "localhost" seems a sufficient default over this localdomain. redhatism.

I like Fedora-XXXXXXXX for default hostname. If I don't care to set a hostname it would be an ok hostname for my machine. I would however like if the hostname setting would be more prominent in the installer. Possibly generating based on my name along the lines of:  fredriks-laptop.rambris.lan
Making the choice it more prominent is probably not necessary, if we
provide a nice default. Although it probably wouldn't hurt. The hostname
could be displayed in the summary or maybe the user creation dialogue
('Create user "user1@Fedora-123345"'?).

Anaconda having a distinct panel explicitly for setting the hostname, along with some knobs for setting the default, depending, for example, on if we've already gotten an IP during PXE, would be a good thing IMO.

Prompts and options would help with some kickstart situations, where one would like a chance to permanently specify it during install regardless of user accounts or install-time networking, and before we reboot for the first time.
