30.2.3. 核​​​​​​​心​​​​​​​

When the kernel is loaded, it immediately initializes and configures the computer's memory and configures the various hardware attached to the system, including all processors, I/O subsystems, and storage devices. It then looks for the compressed initramfs image(s) in a predetermined location in memory, decompresses it directly to /sysroot/, and loads all necessary drivers. Next, it initializes virtual devices related to the file system, such as LVM or software RAID, before completing the initramfs processes and freeing up all the memory the disk image once occupied.

接​​​​​​​著​​​​​​​核​​​​​​​心​​​​​​​會​​​​​​​建​​​​​​​立​​​​​​​一​​​​​​​個​​​​​​​ root 裝​​​​​​​置​​​​​​​，掛​​​​​​​載​​​​​​​ root 分​​​​​​​割​​​​​​​區​​​​​​​為​​​​​​​唯​​​​​​​獨​​​​​​​，並​​​​​​​釋​​​​​​​放​​​​​​​所​​​​​​​有​​​​​​​未​​​​​​​使​​​​​​​用​​​​​​​的​​​​​​​記​​​​​​​憶​​​​​​​體​​​​​​​。​​​​​​​

這​​​​​​​時​​​​​​​核​​​​​​​心​​​​​​​已​​​​​​​經​​​​​​​載​​​​​​​入​​​​​​​記​​​​​​​憶​​​​​​​體​​​​​​​和​​​​​​​運​​​​​​​算​​​​​​​。​​​​​​​但​​​​​​​是​​​​​​​，由​​​​​​​於​​​​​​​尚​​​​​​​未​​​​​​​載​​​​​​​入​​​​​​​任​​​​​​​何​​​​​​​使​​​​​​​用​​​​​​​者​​​​​​​應​​​​​​​用​​​​​​​程​​​​​​​式​​​​​​​至​​​​​​​系​​​​​​​統​​​​​​​中​​​​​​​，系​​​​​​​統​​​​​​​並​​​​​​​不​​​​​​​能​​​​​​​實​​​​​​​際​​​​​​​上​​​​​​​執​​​​​​​行​​​​​​​任​​​​​​​何​​​​​​​運​​​​​​​作​​​​​​​。​​​​​​​

核​​​​​​​心​​​​​​​執​​​​​​​行​​​​​​​ /sbin/init程​​​​​​​式​​​​​​​來​​​​​​​設​​​​​​​定​​​​​​​使​​​​​​​用​​​​​​​者​​​​​​​環​​​​​​​境​​​​​​​。​​​​​​​
