In my system, there’s currently 2 x 2000GB Samsung SSD 980 PRO 2TB + 2 x 4001GB Samsung SSD 870 installed. 1 NVME (2GB) and 1 SATA (4GB) each for CachyOS and Windows 10. It’s a dual-bool setup with Limine. My goal is to phase-out Win10 at some day in the future, as I’m not going to install Win11 for known reasons In Windows, I just installed the OS itself and the most important software (the apps I use daily or any low-level software) into the C: drive which is the super-fast NVME M2 device. Everything else goes to the big but slightly slower SATA SSD. How could I archive something like that in CachyOS? I understand there are some conventions in Linux that define the purpose of directories, such as /var, /opt, /usr/ and /bin. These basically say where software is installed. While in Windows we have drive letters, in in Linux we mount partitions to certain directories into one single tree. Most of the time, I install software using pacman, yay/AUR or the KDE tools. As you can see in the screenshot above, I’ve mounted the 4GB SATA to into my user’s /home directory. Ideally, less used software would go there instead of the standard directories such as /var. Is this even a good idea for Linux or should I go with some other concept? In this scenario, I’d move bigger stuff such as games or my local AI stack (models) docker images, QEMU KVMs to the SATA. Some of my AI-tools are “self-managed” meaning, I just clone & fetch Github repos, then compile everyting inside, so that’s easy. In many programs the destination can be chosen, but how about the “standard” stuff, coming from pacman/yay ?
