Use -L for a permanent change and -U to revert it.
Use -L for a permanent change and -U to revert it.
You're facing a common setup challenge when installing Arch Linux. Since you're using an MBR partition table, the official guides focus on GPT tables. When running genfstab, you'll need to decide between -L and -U depending on whether you want to update the GUID partition table or just the file system entries. Both options are valid, but ensure you understand what each does before proceeding. Let me know if you need further clarification!
It's best to consistently apply -U. Labels may alter and cause system issues.
-L will assign a label to each disk, while -U will use a UUID for identification. You should execute the command you mentioned to set up the mounts.
