Problem
After applying a Build Kit to a RHEL image in Azure, the system now boots in emergency mode
Solution
Remove the below script and execute the hardening script, otherwise server will go to emergency mode.
Remove /root/CISHardening/CIS-LBK/RHEL8/functions/recommendations/nix_vfat_filesystem_disabled_rec.sh
In Azure environment, there is a filesystem /boot/efi which uses vfat format by default. The above script is creating the kernel module, which is blocking to mount the mandatory /boot/efi filesystem which leads emergency.
Server Emergency mode Can't boot, failed to mount /boot/efi on RHEL - Red Hat Customer
