I’m currently using Ubuntu and I want try a different distro but so far the only one I’ve tried was Porteus but I had an issue where Porteus wouldn’t boot if it was installed on top of ext4 but would boot fine if it was installed on top of fat32, which is also another potential problem because Porteus requires a save file for persistence when using Windows filesystems. If there is a problem where my computer can’t boot with an ext4 filesystem, Ubuntu doesn’t have this problem because sda1/2/3 all use a different filesystem.
If I’m correct on this, would I be better off trying Porteus on ext3/2 and hoping it works or just use it with fat32 and have a separate partition formatted for ext4 to serve the same purpose as sda3 in Ubuntu and possibly store the save file (if I have the correct understanding of how save files work).
Also, I would just use NTFS but not only have I heard that it has issues with Linux, I’ve had issues using it with Linux, so I’m using fat32 for stability.
Why porteus? That seems like a very specialized distro, and the fact that it’s optimized to run on usb sticks might have something to do with the filesystem issue. If this is just for a laptop or desktop then I’d recommend running a mainstream distro meant to be used on a pc. If you do that then ext4 will work fine. If you’re comfortable with ubuntu and not too freaked out by working in the terminal then why not try endeavourOS or something along those lines?
