With significant firstboot output, there was a tendency
for tail to be killed before it relayed all the content.
Change to run the firstboot in a subshell in the background,
and have tail explicitly run until that subshell naturally
exits and then tail will cleanly exit
The 'profile' variable notably induces dracut to be excruciatingly slow,
mitigate chance by putting confluent before apikey, mgr, and profile.
Further, it has been requested to have the scripts use same name on
server for directory moving forward. Implement this request while
allowing existing OS profiles to keep working.
Sometimes firstboot scripts want to reboot.
In such a case, start firstboot once, and if reboot prevents completion,
then next boot will updatestatus, but not run firstboot scripts and
deregister itself.
Use a more neutral name for the deployment server target.
It is still ipv4 only for the moment, but easier to pull in
ipv6 support when not having to change paths that don't care.
Also add 'mgt_server' rather than 'ipv4_server'. Will move to this.
The server should be able to dictate the right address without the
deploymennt image having to keep track.
