Under Red Hat Enterprise Linux, it is possible to change the default runlevel at boot
time.
To change the runlevel of a single boot session, use the following
instructions:
When the GRUB menu bypass screen appears at boot time, press any key
to enter the GRUB menu (within the first three seconds).
Press the [a] key to append to the
kernel command.
Add
<space><runlevel>
at the end of the boot options line to boot to the desired
runlevel. For example, the following entry would initiate a boot
process into runlevel 3:
grub append> ro root=/dev/VolGroup00/LogVol00 rhgb quiet 3 |
