RHEL 7: how to add vfat and fat kernel module to initramfs from dracut prompt [solved]

Hello fellow forum members,

Due to CIS benchmark hardening our automation tools has blacklisted the installation of vfat and fat kernel modules.

This has caused a reboot failure on an Azure VM that uses a vfat filesystem for the luks vault.

Has anyone been able to add the 2 missing kernel modules to the initramfs to be able to boot.

Solution: unpack the current initramfs, add the missing modules and run depmod -a, repack.

always make a backup copy of the initramfs you manually try to fix

Regards,
