I would not worry about virtual memory usage. Virtual memory can include memory mapped files and does not indicate actual ram usage - only the address space that the program has opened at some point. There is little point in worrying about it.

IMO the best thing is to just start using it. You will start to pick things up fairly quickly then. Puzzles don’t often ingrain different ways todo things and often focus on weird or niche things that don’t come up as often. They can be a nice supplement to not a substitute for just using it in real world usescases.

I do also find it helpful to read the shortcut keys on their site to get a feel for what is available. You won’t remember everything but it can be useful to know what is possible. Then when you hit a problem you may remember reading about something that can help and go look it up again.

Just dont format the drive when installing a new distro. BTRFS or not you can delete the system folders manually first if needed but I believe that some if not all distros will delete the system folders for you (at least ubuntu used to do this last I tried). And if not you can do it manually.

It does not matter if you have a separate partition or not for /home installers won’t touch it if it already exists except to create a new user if needed. Remember, all the installers do is optionally format the drives, mount them then install files into those drives. If you skip the formatting and manually do that partitioning (or using an existing partition layout) it will still mount and write to the same places regardless of it they are separate partitions or not. So a separate partition does not add any extra protection to your home files at all.

But regardless of what you do you should ALWAYS backup your home data anyway. Even with separate partitions or subvolumes the installer can touch or delete anything it wants to and you can easily click the wrong button or accidentally wipe thing. At most preserving your home saves you from restoring from a backup it should not be done instead of backup.

There is no problem with having home on a different disk. But why do you want swap on the slower disk? These would benefit from being on the faster disks. Same with all the system binaries.

Personally I would put as much as possible on the faster disk and mount the slower somewhere that the speed matters less. Like for photos/videos in your home dir.

/boot can be anywhere though if you are getting a grub error that suggests the UEFI firmware is finding grubs first stage but grub is having issues after that. Personally I don’t use grub anymore, systemd-boot is far simpler as it does not need to deal with legacy MBR booting.

My point is the different levels of just working are subjective, not objective. I personally have spent far more time fixing bugs or just reinstalling ubuntu systems then I have over the same period for Arch systems. So many of my ubuntu installs just ended up breaking after a while where I have had the same Arch install on systems for 5+ years now. Could never get a Ubuntu system to last more then a year.

Everyone has different stories about the different OSs. It is all subjective.

You can cherry-pick examples of problems from every OS. That is my point. They all have issues that you may or may not encounter and quite a few that would make people from other OSs scratch their head and think what the hell the devs are thinking. Pointing out one issue of one OS does not change any of that.

Which is proven by the other replys to your comment - others dont find this issue to be as show stopping as you do and just live with it or dont use it at all. How many issues do you do the same for on your favorite OS?

There is no perfect OS that just works for everyone. They are all software so they all have bugs. People how say an OS just works have never hit those bugs or have gotten used to fixing/working around or flat out ignoring them.

This is true of all OSs, including Windows, Linux and MacOS. They are all differently buggy messes.

Linux is the buggy mess that works best for me though.

Might I add the idea that your terminal emulator must support your shell is utterly ridiculous?

TBH I am starting to come around to the idea of a tightly integrated shell and terminal emulator support. There are just things you cannot do with these being separate things. I am very tempted to explore the idea from the other end though - writing a shell that has a emulator built into it (like screen/tmux basically are). But I do think that this integration is needed for any per command features that is not just printing out a prompt.

It would be interesting to see what could be done with this type of integration but will likely break support for existing shells. Unless you maybe launch a shell for each command you run or something 🤔. Would like to seem more people experimenting with stuff like this and see what new things we could drive forward. We have been stuck with the current tty system since like the 80s to support devices that just dont exist anymore.
