[gentoo-user] Gentoo Runlevels while booting

[gentoo-user] Gentoo Runlevels while booting

[Ryan Viljoen]

I have been setting up a server with SuSe on it (dont ask why SuSe...
the developers of one of the apps required will only support SuSe).

Anyway I noticed that when SuSe boots, after its gone through the boot
runlevel it switches to runlevel 5 and loads up kdm while completing
runlevel 3. Now this is great cause you can login and such assuming
you dont have any network dependent login services (NIS and NFS
shares).

So I was wondering if this was possible with Gentoo. Its not as simple
as adding xdm to the boot runlevel. dont worry I tried...

Any thoughts?

it's loading things in parallel.  I believe I saw something on this  
list last week about gentoo being able to do that...seems it was  
masked, though...

You can start things in parallel on Gentoo as well by setting
RC_PARALLEL_STARTUP in /etc/conf.d/rc.

However this does not affect the display manager.  Gentoo will only
start the display manager after all other init services have been run.
 See the comments in /etc/init.d/xdm, and the /etc/inittab file.

must be this

# /etc/conf.d/rc: Global config file for the Gentoo RC System

# Set to "yes" if you want the rc system to try and start services
# in parallel for a slight speed improvement.

RC_PARALLEL_STARTUP="no"

Gentoo extends init's runlevel concept with its own concept, called 
softlevels. You can create as many softlevels as you like/need.

Just create an new directory for your runlevel in /etc/runlevels, populate 
it with the services you want to start in this runlevel (rc-update add 
myservice myrunlevel) and update your bootloader config so that you can 
select the desired runlevel at boot time, i.e. for grub you would add 
"softlevel=myrunlevel" to the "kernel" line.

HTH...

The Gentoo xdm script waits until all other init services
(particularly getty sessions) are started, to allow for those display
managers that don't know what tty to run on, and may cause a conflict
and a dead keyboard.  See the comments in /etc/init.d/xdm.

However, if your display manager (in my case kdm) is properly
configured, and doesn't conflict with /etc/inittab, you can start the
display manager much earlier in the startup sequence, but you have to
make your own init script for that.  This is what I did, based on the
xdm init script:

# Distributed under the terms of the GNU General Public License, v2

# Start X Font Server before X
depend() {

}

source /etc/profile.env

cmdline_opt() {
        if [[ "$#" -ne 1 ]]; then
                return 1
        fi

        for opt in $(</proc/cmdline); do
                case ${opt} in
                        ${1}) eval ${1}="true" ;;
                esac
        done
}

nox() {
        # Don't start X if we were passed 'nox' at boot (#83680)
        cmdline_opt nox

        if [[ "$?" -ne 0 ]]; then
                return 1
        fi

        if [[ -n "${nox}" ]]; then
                return 0
        else
                return 1
        fi
}

start() {
        if nox; then
                einfo "Skipping ${EXE}, received 'nox'"
        else
                ebegin "Starting kdm"
                start-stop-daemon --start --quiet --exec $(which kdm) \
                        --pidfile /var/run/kdm.pid &>/dev/null
                eend $? "Error starting kdm"
        fi

}

stop() {
        local retval=0
        local curvt="$(fgconsole)"

        ebegin "Stopping kdm"
        start-stop-daemon --stop --quiet --exec $(which kdm) \
                --pidfile /var/run/kdm.pid &>/dev/null
        retval=$?

        chvt "${curvt}" &>/dev/null
        eend ${retval} "Error stopping kdm"
        return ${retval}
}

Look at /etc/inittab and /etc/runlevels. You can define any customised 
runlevel.
