BootFlags
This page documents the list of flags that can be passed to the kernel at boot and how they affect various components of the system.
Flag |
System Component |
Description |
root=DEV |
kernel/initrd |
Passes DEV as the root partition to mount during startup. If an initrd is used, this option is handled by the scripts inside the initrd (this the default behavior, and required for LVM or RAID root partitions). If an initrd is not used, this is interpreted by the kernel. |
ro |
kernel/initrd |
Tells the kernel to mount the root partition as read-only on boot. This allows file system checks to be performed before the system boots and remounts the root partition as read-write. |
quiet |
kernel/initrd |
Tells the kernel to show only urgent messages during boot. This is useful for debugging, and is generally removed along with the splash option. |
splash |
usplash |
Starts the splash screen during boot. |
