Root File system mounting

[Sundar_7]

This is going to be a trivial question.

I am really wondering how root file system is mounted.

I could recollect kernel mounts root whenever the system boots.

But then scripts preinitrc and bcheckrc also has some reference to mounting root.

Any inputs ?

Thanks & Regards

root, /stand (if you have one) and primary swap are all activated very early in the boot process.

Have a look at 'man lvlnboot'. lvlnboot stores pointers to these volumes for use by the boot process.

Note that even when booted in LVM maintenance mode, root, stand and swap are mounted/inuse, even though vg00 is not activated.

bcheckrc (amongst other things) calls /sbin/lvmrc to activate volume groups.

pre_init_rc runs fsck on the root filesystem.
