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.
So I wasn't the only victim of that installer. :(
right, my problem was that Debia (at least the linucnc one) forgot where
it was installing stuff and only wanted to use the last found /dev/sd*
in the grub/initrd image. I promised someone on the forum/list that I'd
try to see if that is a Debian issue, or if the bug was introduced later
in the distro.
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
On a bigger network, yes indeed.
Yeah and I have a bunch of different gadgets, that don't even have a
filesystem, and boot using dhcp/bootp (like wemo and D-Link stuff)
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.
I find I have a static ip as long as I don't putz with the routers MAC.
So one of them is cloned from the other. :)
Just wondering? Why would you clone that MAC? I assume you use the
same IP on both those NICs? Else ARP would be unhappy.
Did you do that between your modem and router or so?
but... whatever works, right?

Well, I did manage to get that one nstalled. The Debian installer

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.
