以下为wiki上搜到的说明~Note: If your system has more than one hard drive, the installer will default to using UUID rather than the sdx naming scheme, for consistent device mapping. Utilizing UUID has several advantages and may also be preferred to avoid issues if hard disks are added to the system in the future. Due to active developments in the kernel and also udev, the ordering in which drivers for storage controllers are loaded may change randomly, yielding an unbootable system/kernel panic. Nearly every motherboard has several controllers (onboard SATA, onboard IDE), and due to the aforementioned development updates, /dev/sda may become /dev/sdb on the next reboot. (See this wiki article for more information on persistent block device naming. )
看来udev带来的“好处”有很多哇,能够支持卷标定义,UUID定义,用sdx来描述grub或者fstab就悲剧了~ |
