@viniciusferrao Thank you for your contribution.

I am trying to validate that this works in our environment.

I am running into problem when provisioning diskfull VM with either OL8.3 or OL7.9
The problem appears to be %include /tmp/repos line in OL .tmpl file.

Same line is there for RHEL8 .tmpl file.
When provisioning RHEL8, there is a file /tmp/repos on the node with this content:

# cat /tmp/repos
url --url http://<xCATMN>:80//install/rhels8.3.0/x86_64
#

But when OL8 or OL7 is being provisioned, no such file is on the node and it fails with:

An error occurred during reading the kickstart file: Unable to open input kickstart file: Error opening file: [Errno 2] No such file or directory: '/tmp/repos'

I can comment that line out from the OL .tmpl file and provisioning succeeds.
Did you see a similar problem on your systems ?

I didn't tested with stateful nodes, only stateless... I will do some testing with stateful to replicate the issue.

@gurevichmark I think I've found the issue, it's probably on xCAT-server/lib/perl/xCAT/Template.pm in line 302:

if ($platform =~ /^(rh|SL|centos|fedora)$/) {

Instead of removing it from the kickstart file, I think it's better to just fix the template file and keep things persistent between EL releases.

Hi @gurevichmark, I've tested the last commit with Legacy BIOS and UEFI:

[root@cabecudo ~]# lsdef -t node n01 | grep install
    currstate=install ol8.3-x86_64-compute
    provmethod=ol8.3-x86_64-install-compute
    status=installing
[root@cabecudo ~]# lsdef -t node n02 | grep install
    currstate=install ol8.3-x86_64-compute
    provmethod=ol8.3-x86_64-install-compute
    status=installing

Both are working now:

[root@cabecudo ~]# lsdef -t node n01 | egrep "install|status"
    provmethod=ol8.3-x86_64-install-compute
    status=booted
    statustime=04-16-2021 18:01:10
[root@cabecudo ~]# lsdef -t node n02 | egrep "install|status"
    provmethod=ol8.3-x86_64-install-compute
    status=booted
    statustime=04-16-2021 18:02:12

Something went messy with the CI/CD again, can you retry it?
