9.4.3. 根​​​​​​​文​​​​​​​件​​​​​​​系​​​​​​​统​​​​​​​和​​​​​​​ GRUB

The use of the term root file system has a different meaning in regard to GRUB. It is important to remember that GRUB's root file system has nothing to do with the Linux root file system.
GRUB 根​​​​​​​文​​​​​​​件​​​​​​​系​​​​​​​统​​​​​​​是​​​​​​​指​​​​​​​定​​​​​​​设​​​​​​​备​​​​​​​的​​​​​​​最​​​​​​​顶​​​​​​​层​​​​​​​。​​​​​​​例​​​​​​​如​​​​​​​,映​​​​​​​像​​​​​​​文​​​​​​​件​​​​​​​ (hd0,0)/grub/splash.xpm.gz 位​​​​​​​于​​​​​​​ (hd0,0) 分​​​​​​​区​​​​​​​(实​​​​​​​际​​​​​​​上​​​​​​​是​​​​​​​系​​​​​​​统​​​​​​​的​​​​​​​ /boot/ 分​​​​​​​区​​​​​​​)的​​​​​​​顶​​​​​​​层​​​​​​​(或​​​​​​​根​​​​​​​)的​​​​​​​ /grub/ 目​​​​​​​录​​​​​​​。​​​​​​​
然​​​​​​​后​​​​​​​,以​​​​​​​内​​​​​​​核​​​​​​​文​​​​​​​件​​​​​​​的​​​​​​​位​​​​​​​置​​​​​​​为​​​​​​​选​​​​​​​项​​​​​​​的​​​​​​​ kernel 命​​​​​​​令​​​​​​​被​​​​​​​执​​​​​​​行​​​​​​​。​​​​​​​一​​​​​​​旦​​​​​​​ Linux 内​​​​​​​核​​​​​​​被​​​​​​​引​​​​​​​导​​​​​​​,它​​​​​​​设​​​​​​​立​​​​​​​ Linux 用​​​​​​​户​​​​​​​所​​​​​​​熟​​​​​​​悉​​​​​​​的​​​​​​​根​​​​​​​文​​​​​​​件​​​​​​​系​​​​​​​统​​​​​​​。​​​​​​​之​​​​​​​前​​​​​​​的​​​​​​​ GRUB 根​​​​​​​文​​​​​​​件​​​​​​​系​​​​​​​统​​​​​​​和​​​​​​​它​​​​​​​所​​​​​​​挂​​​​​​​载​​​​​​​的​​​​​​​文​​​​​​​件​​​​​​​系​​​​​​​统​​​​​​​都​​​​​​​不​​​​​​​再​​​​​​​被​​​​​​​使​​​​​​​用​​​​​​​;它​​​​​​​们​​​​​​​只​​​​​​​在​​​​​​​引​​​​​​​导​​​​​​​内​​​​​​​核​​​​​​​文​​​​​​​件​​​​​​​时​​​​​​​存​​​​​​​在​​​​​​​。​​​​​​​
Refer to the root and kernel commands in 第 9.6 节 “GRUB 命​​​​​​​令​​​​​​​” for more information.
