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.) -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
