Description of problem:
Kernelcmd not being honored during provisioning using Kickstart default PXELinux template
I am trying to set net.ifnames=0 and biosdevname=0 to kickstart a rhel-7 host using the “Kickstart default PXELinux” template. I want to use the eth naming convention for the interfaces. Here is the command I use to create the host.
```
hammer host create \
--name tests001 \
--architecture x86_64 \
--build true \
--content-view rhel-7-server \
--domain local.net \
--enabled true \
--lifecycle-environment rhel-7-server_08-08-2022 \
--location MyLocation \
--managed true \
--medium rhel-server-7.7-x86_64-dvd-20190728 \
--operatingsystem rhel-server-7.7-x86_64 \
--organization MyOrganization \
--overwrite true \
--partition-table "rhel-7-server-dynamic-xfs" \
--product rhel-7-server-rpms \
--provision-method build \
--pxe-loader "PXELinux BIOS" \
--interface "mac=08:00:27:cc:2a:40, \
ip=192.168.0.145, \
type=interface, \
managed=true, \
primary=true, \
provision=true, \
subnet=192.168.0.0, \
virtual=false" \
--interface "mac=08:00:27:f0:6d:8a, \
ip=192.168.1.145, \
type=interface, \
managed=true, \
primary=false, \
provision=false, \
subnet=192.168.1.0, \
virtual=false" \
--parameters "selinux-mode=permissive, \
bootloader-append=selinux=1 audit=1 transparent_hugepage=never, \
time-zone=Etc/GMT, \
disable-firewall=false, \
redhat_install_agent=false, \
redhat_install_host_tools=false, \
redhat_install_host_tracer_tools=false, \
activation_key=rhel-7-server-latest, \
atomic=false, \
subscription_manager=true, \
subscription_manager_auto_attach=false, \
subscription_manager_certpkg_url=http://formn001/pub/katello-ca-consumer-latest.noarch.rpm, \
subscription_manager_org=MyOrganization, \
package_upgrade=true, \
loader_timeout=2, \
kernelcmd=net.ifnames=0 biosdevname=0"
```
After I run the command, I navigate to “Hosts > Provisioning Templates > Kickstart default PXELinux” and select Preview. I can see the APPEND line correctly shows “net.ifnames=0 biosdevname=0”.
`APPEND initrd=boot/rhel-server-7-7-x86_64-dvd-20190728-qWmnKQBMBQsJ-initrd.img net.ifnames=0 biosdevname=0 network ksdevice=bootif ks.device=bootif BOOTIF=01-08-00-27-cc-2a-40 ks=http://formn001.local.net/unattended/provision?token=3d07f52d-740d-4e3a-b9bd-07068bdbfa8d kssendmac ks.sendmac ip=192.168.0.145::192.168.0.1:255.255.255.0:tests001.local.net::none nameserver=192.168.0.12 nameserver=192.168.1.12`
After that I start the new VM using Oracle VM VirtualBox and boot to the network. The correct PXE menu is displayed, and I hit TAB to see the pxe command line. I see everything as written in the APPEND line above except for net.ifnames=0 and biosdevname=0. If I continue to provision the host everything is setup correctly except net.ifnames=0 and biosdevname=0 are not honored and I do not get the eth naming convention. I can manually enter net.ifnames=0 and biosdevname=0 on the pxe command line and it works correctly, but that is not feasible to provision hundreds of hosts.
If I clone the template and manually add net.ifnames=0 and biosdevname=0, I can see it on the pxe command line, the options are honored, and I get the eth naming convention.
Version-Release number of selected component (if applicable):
satellite 6.12.0
How reproducible:
Always
Actual results:
net.ifnames=0 and biosdevname=0 not showing on the pxeboot command line
Expected results:
Expecting net.ifnames=0 and biosdevname=0 to show on the pxeboot command line
