noauto?????
There is no need to mount /boot unless you install new kernels or update
your bootloader configuration.
Many people prefer to mount it
read-only, though.
/dev/mapper/anzu_main-usr_lv /usr ext3 noatime,ro,defaults 0 2
I understand why this is ro; why then is /boot rw?
As I said, Manoj probably only mounts /boot to install new kernels, and
then he wants to write to it.
/dev/mapper/anzu_main-home_lv /home ext3 noatime,rw,nosuid,nodev 0 2
What does nodev mean? (My google fu must be lacking.) Is "Do not
interpret character or block special devices on the file system." just
extra security so that a rogue app doesn't try to create a device file
anywhere but /dev?
It does not prevent _creating_ device files, but it prevent _accessing_
them and the underlying hardware.
