Some versions start manifesting nvme devnames with 'c', which
are to be used to interact with multipath to have raw devices
backing a traditional nvme device.
If the ip command shows altnames, do not
let the altnames interfere with locking
on to linktype.
Further, use show dev instead of grep to be more specific.
When booting and infiniband comes up as the 'get started' nic,
make the entry use correct type so as to avoid
confusion later, particularly when confignet comes along to fixup
the configuration.
Main difference from EL8 is different grub strategy. To cope, capture
the uuid of new /boot and manipulate the
stub grub.cfg with the right uuid.
In EL8, the efi has the main grub, EL9 changes to have /boot host the 'real' grub,
causing us to have to modify the stub grub.
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
It is likely that a client connects from fe80::, which
is explicitly omitted from ssh principals.
This time, have the client provide all currently set IP addresses
and the server will make a determination.
There remains the possibility it misconfigures a nic and tries to use that,
inducing failure. One strategy would be to filter the addresses and
only provide from the 'current' interface. Another is to just take
the hit as the node is likely going to suffer a lot from such a
misconfiguration anyway.
