Proc/Cpuinfo - Red Hat ENTERPRISE LINUX 5 - DEPLOYMENT Deployment Manual

Chapter 3. The proc File System
This output tells us the following:
ro
The root device is mounted read-only at boot time. The presence of ro on the kernel boot line
overrides any instances of rw.
root=/dev/VolGroup00/LogVol00
This tells us on which disk device or, in this case, on which logical volume, the root filesystem
image is located. With our sample /proc/cmdline output, the root filesystem image is located
on the first logical volume (LogVol00) of the first LVM volume group (VolGroup00). On a system
not using Logical Volume Management, the root file system might be located on /dev/sda1 or
/dev/sda2, meaning on either the first or second partition of the first SCSI or SATA disk drive,
depending on whether we have a separate (preceding) boot or swap partition on that drive.
For more information on LVM used in Red Hat Enterprise Linux, refer to
HOWTO/LVM-HOWTO/index.html.
rhgb
A short lowercase acronym that stands for Red Hat Graphical Boot, providing "rhgb" on the kernel
command line signals that graphical booting is supported, assuming that /etc/inittab shows
that the default runlevel is set to 5 with a line like this:
id:5:initdefault:
quiet
Indicates that all verbose kernel messages except those which are extremely serious should be
suppressed at boot time.
