I am trying to boot a grub entry for CentOS 8

menuentry "Server Install CentOS 8" { linux /boot/vmlinuz noverifyssl ks= https://devgeis.LayeredSolutionsInc.com:443/kickstart/ks_update_to_server8.c... biosdevname=0 net.ifnames=0 ksdevice=eth0 ip=192.168.1.13 gateway=192.168.1.1 netmask=255.255.255. 0 nameserver=192.168.1.1 inst.sshd sshd=1 initrd /boot/initrd.img }

When booting it says that "ip=192.168.1.3" Sorry unknown value.

This works on CentOS 7. How do I specify the IP/SN/GW for CentOS kernel line?

That method was listed as deprecated in EL-7 and I think the method you need to use now is http://man7.org/linux/man-pages/man7/dracut.cmdline.7.html

ip=192.168.1.13::192.168.1.1:255.255.255.0:hostname.goes.here:eth0:on:1500:<mac-address-of-eth0>

If MAC address is mandatory here, it becomes extra hassle compared to kickstart build I was using until now...

The mac address isn't mandatory but you are then up to the whims of the kernel, dracut, and whatever else is involved on what gets picked for eth0. It works less often than it used to for me so I would end up on a very very long rant tag.

(Is <rant> tag due above ? ;-)

I am going to guess that should work, but I have not had much luck with ethX interfaces with dracut

Thanks for the information.

What "insanity". Take a perfectly good syntax and muck it up like that. The developer that "lost" backward compatibility for that mess needs a couple more drinks or something.

The problem I think was that the syntax was one which worked for one OS and the dracut is meant to work for all Linuxes.. so they worked out a set of items which worked for Debian, SuSE, Mandrake, Fedora. The syntax change I think landed in Fedora right after RHEL-6 and was in RHEL-7 from the beginning. As the web page goes over, there are several different syntaxes which can be used for different environments.

[At this point i have been having to hack that syntax for 7 years so I have a severe case of Stockholm syndrome.]
