Hello Gene,
yes when in doubt, with a distro I don't know, I do disable drives, or
unplug them.
(learned that lesson with installing Ubuntu one time years ago, and it
reclaimed all space from all drives.). So I did in this case, but
usually (I work witRHEL and Centos a lot) I don't it's too much work, I
have several machines.
Host files wouldn't work for me, I have a bunch of IoT devices (wifi
enabled light switches, electrical outlets (dozen and a half) and
cameras (10) and a dozen motion detectors, and they all boot trying to
getan IP address using bootp/dhcp. Also, I have different physical
networks (to spread out traffic from access points), using a Cisco
router and 3 Cisco switches.
Keeping track of everything would be too much work
However DHCP is not a fancier thing instead of a hosts file, that would
be DNS. DHCP is used for configuringnetwork devices (like NICS and IB
cards etc, manually configuring network device is done with network
scripts (they are usually in /etc/sysconfig/network-scripts).
It is better to avoid using hosts files for "regular" networks, updating
them is a pain. There is still a good use for hosts files though, in HPC
they are used to "list" the compute nodes, io nodes etc etc. Keeping
track of those is usually not a problem, because the hosts file is the
same for all nodes, and because they boot diskless there is actually
only one version of the file around that gets used on the diskless/vnfs
image
I have a few domain names also, one I have hosyed somewhere for some
external stuff, and I have two here that I just use for kicks and
giggles. I use DDNS though, I am cheap and don't want to pay for a
static IP, and I don't really need it.
but... whatever works, right?

If you'd install on /dev/sda and the last device is /dev/sde, ireally
wants you write that last one
in the grub conf and also in the intram image.
I didn't have any network issues, but I use DHCP. When the installer
starts the network stuff, it
uses what it gets from that dhcp server. (It wants a host-network
name, but I left the domain name
blank. (shouldn't matter anyway)
You might want to set up a dedicated IP for the MAC on that machine,
some routers don't like unkown MAC addresses too much.
I've found its generally smart to remove the cables from drives that are
not to be touched by the install, and plug them in and add them
to /etc/fstab later.
I don't use dhcp in house. I long ago decided a hosts file was a more
secure network. And I moved it off the base block of 192.168.xx.yy. My
resolv.conf is a real file, and sets the nameserver addy to the router,
searches hosts nameserver, and if dnsmasq doesn't have it cached, querys
the nameserver my router got from my ISP via dhcp. Network access from
any of my machines is transparent as this address block I use in NAT'd
by iptables in either of my routers, I have 2 just in case, the 2nd one
cloned to the same MAC. Since I'm a fixed address, my web registration
at namecheap is $15 & change for 5 years. I just made sure namecheap had
the correct card number as the auto renewal is today. My simple web
page runs in a sandbox/permissions jail via a separat NAT rule. In
nearly 20 years, no one has managed to get thru dd-wrt and attack me. I
don't run any local firewalls except in the router. And It all Just
Works.
Hope this helps in some way.

Well, I'll be dipped. I saw no announcements go by. Thats likely a
better install then since my stretch installs have all had network
problems involving routing.

r13? Where did you get that? My copy has no r13 in the filename.
