I have been running Debian for a number of years (about 13) and am generally satisfied with the OS. However, I am becoming more and more convinced that Systemd is like a cancer and is spreading out of control. My desktop has two SSD's, each with Debian Bullseye installed. Let's call them drive A and drive B. Drive A is my daily driver and drive B is a fully bootable backup. I have been giving serious thought to migrating drive B to Devuan. I have read the page on migrating from Bullseye to Devuan Chimaera and it seems pretty straight forward. However I have some questions that I would like answered before I take the leap.

1. Can I do the migration using a terminal, such as the xfce terminal, so that I can keep the web page instructions in view while doing the migration? I would assume so, but assuming can be risky.
2. Since I am using grub on drive A will the update properly reconfigure grub on that drive? Actually, both drives have an MBR and grub is installed on both drives but A is the primary go to drive.
3. I have two pinned packages (I don't like the updated versions). Will those pinned packages cause any issues during migration?
4. I also have an older version of Tcl and Tk installed (8.4), but since those version were installed by the specific version number I don't think that should cause any issues. Any thoughts on that?

I think I had some other question but I can't remember it. Old age sometimes does that. LOL!

I will be awaiting a response with pleasant anticipation.

ps. Good to see some familiar and trustworthy members here that are also present on the Debian forum.
