Re:Edgy Eft "UUID's" in fstab

Yes, UUIDs are somewhat annoying, but they're the best solution we have:


  • Disk labels aren't guaranteed to be unique.


  • The kernel's device paths aren't constant enough -- move your SCSI interface card to a different slot and your system doesn't boot any more..?


  • Device names aren't constant either -- they depend on module load order. "Worse": the kernel is migrating to scanning its hardware in parallel. Therefore, which device ends up as<nobr> <wbr></nobr>/dev/sda will be entirely random Real Soon.


Besides, there's a nice tool at<nobr> <wbr></nobr>/sbin/blkid which will happily print a list of device names, filesystem labels and UUIDs for you. Even if you aren't root.


In other words, this (a) Just Works, and (b) is *way* better than anything you get with Windows. So stop complaining.<nobr> <wbr></nobr>;-)
