Adding IOMMU Bash Script

[initcyber]

Ran into an interesting idea today, when I was setting iommu across all three of my nodes, I started down the path of updating grub on my 2nd system, I realized I had systemd installed (instead of the typical grub I was used to). Then I got to thinking about automation using ansible to figure out if my system (or any system) has systemd or grub (using "ps -p 1 -o comm=") then updating either the grub file or the /etc/kernel/cmdline file as needed (my bash scripting skills = trash)

I went to see if you had a script that already automated this using bash but alas, there was none. Just throwing out an idea here since your repository is amazing and I want to contribute an idea: Maybe some sort of script to add to your list of scripts for the community that would:

A) figure out if the system is running Grub or systemd boot (maybe exit if it can't be determined) - Bash command : ps -p 1 -o comm=
B) determine what type of processor is being used (AMD vs Intel) - Maybe " lscpu | grep Model " ?
C1) For systemd (Intel , AMD remove the intel line) : echo "intel_iommu=on iommu=pt" >> /etc/kernel/cmdline
C2) For grub (Intel, AMD remove the intel linke) : sed /GRUB_CMDLINE_LINUX_DEFAULT="/ intel_iommu=on iommu=pt"
D1) For systemd : pve-efiboot-tool refresh
D2) for grub: update-grub

Something like that. I'm not a scripting pro by any means, just trying to make the project better.
