installing of linxcnc

Sure you can delete your swap space and most stuff will just work. Some apps won't. SSD space is so much cheaper than 10yr. ago, do your pc a favor and allow at least 1GB swap space if you have to cut it short.

Long ago I read swap kills SSDs so I carefully removed swap from all my linux os. After a long time I learned some of my mysterious linux troubles were swap related (because I used no swap space). It seems most stuff just works without swap, but it hurts stability a little, even if you have more RAM than you'll ever use. Also, nowadays the OS and SSDs are designed in ways so swap is not so hard on SSDs.

Nowadays I  make sure to provide swap space bigger than my RAM. Like 64GB RAM and 90GB swap. This allows hibernation to work. Then I completely disable hibernation because I don't like it. go figure. image missing /media/kunena/emoticons/wink.png

If you really need swap space, you can use a file instead of a separate partition. 
 

That works, also. I recall seeing that automatically created on one of my Linux boxes a while back upon install. I don't remember which distro it was. Might have been Ubuntu.

I don't know why this conversation got down to swap drives and building LinuxCNC from source. None of that is necessar. LinuxCNC only requires 4-8 gb RAM but I think I'd lean towards 8 gb today.
Just follow Andy's directions, accept the default partitions and have fun. After all he is the Release Manager so should know a thing or two about how to install his releases!

The author of topic asked for the latest version of LinuxCNC.
The latest version of LinuxCNC is compiled from latest sources...
Compilation of LinuxCNC is easy, easier than many things you have to do after.
Where see you problem?  

I agree, many things are not neccessary, for example PC computer is not neccessary, and LinuxCNC is not neccessary, you could use GRBL  controolled from smartphone, but this is not the subject of the topic.

Modern Linux needs 2 (two) gigabytes of RAM.
Some programs needs more, but LinuxCNC not belongs to them.
My computer I use to write this post (Ryzen 5 with 16 GB of RAM running Firefox on Debian 13.6 with xfce4) uses now 2 GB of RAM, and believe me, this may be less if less memory is installed.

I see, we are on different levels of using Linux...
For me copying whole partition to other disk is normal and often used procedure. I don't need unwanted dependiences, like system not starts without swap partion leaved on old disk. I not need any swap partition, because Linux can use for swap file placed on any mounted partition, and you can turn on/off swap when you need (swapon/swapoff).
Swap file is correct solution, swap partition is a prayer for troubles...

You may use defaults installation settings, and it should works, but why you deny talk about how do it better?
