Hi, We are integrating our 5G Flexran solution on Starlingx and We are using Stx 4.0.1 ISO in AIO-SX mode.

We found that SCTP kernel module not available in stx 4.0.1 ISO, what is the way to persistently install SCTP module ?

1. As per discussion and resolution in "https://bugs.launchpad.net/starlingx/+bug/1894171", it seems that SCTP kernel module is not part of stx 4.0.1 ISO.

[root@controller-0 sysadmin(keystone_admin)]# modprobe sctp

modprobe: FATAL: Module sctp not found.

We then manually downloaded this rpm: "http://mirror.starlingx.cengn.ca/mirror/starlingx/release/4.0.1/centos/distro/outputs/RPMS/rt/kernel-rt-modules-extra-4.18.0-147.3.1.rt24.96.el8_1.tis.8.x86_64.rpm. And after installing this (rpm -i kernel-rt-modules-extra-4.18.0-147.3.1.rt24.96.el8_1.tis.8.x86_64.rpm), the "modprobe sctp" was successful

However, on reboot the SCTP installation is not persistent, we have to again do rpm install.

After manually installing "kernel-rt-modules-extra-4.18.0-147.3.1.rt24.96.el8_1.tis.8.x86_64.rpm", what is the mechanism to persist SCTP kernel module across reboots..
