Slow boot up...

gor0 · 03-01-2015, 08:13 AM

Can someone help me to improve my boot time?

Code:

cd /etc/rc.d
bash-4.3# ls --color
init.d        rc.cgconfig.orig  rc.lxc              rc.syslog
rc.0          rc.cgred          rc.mcelog           rc.sysstat
rc.4          rc.cgred.orig     rc.messagebus       rc.sysvinit
rc.6          rc.consolekit     rc.modules          rc.udev
rc.6.orig     rc.cups           rc.modules-3.10.17  rc.ulogd
rc.K          rc.dnsmasq        rc.modules-3.14.33  rc.wicd
rc.K.orig     rc.font           rc.mysqld           rc.wireless
rc.M          rc.fuse           rc.networkmanager   rc.wireless.conf
rc.M.orig     rc.gpm-sample     rc.nfsd             rc.yp
rc.S          rc.httpd          rc.ntpd             rc0.d
rc.S.orig     rc.inet1          rc.pcmcia           rc1.d
rc.acpid      rc.inet1.conf     rc.php-fpm          rc2.d
rc.alsa       rc.inet2          rc.rpc              rc3.d
rc.alsa-oss   rc.inetd          rc.samba            rc4.d
rc.atalk      rc.ip_forward     rc.saslauthd        rc5.d
rc.autofs     rc.keymap         rc.sendmail         rc6.d
rc.bind       rc.laptop-mode    rc.serial
rc.bluetooth  rc.local          rc.snmpd
rc.cgconfig   rc.loop           rc.sshd

I think I have some wrong ...

tia!

Could you perhaps quantify your current boot time, and your hardware setup (cpu speed, number cpus, memory and hard disk size and type)? You might already be as fast as it can go. And how often do you really boot up ? I have a laptop, which boots in about 3 seconds - how ? - simply because it practically never actually boots, but just comes out of suspend mode. Do I care how long it would take to actually boot on the rare occasion that I switch it off - not a chance in hell !

I suspect 'modules' ...

Don't forget to use JFS with TRIM, and try to shift the maintenance commands into a runscript to fork to the background, or drop them into a cronjob.

Someone here posted a tip on how to do such things, try the Search feature and search GazL's(?) posts for the script hint. It works very well.

rc.modules is needed to load several hardware setups in the background. Don't thinker with it. You should however delete the older rc.modules-3.10.7 and relink the rc.modules symlink to the newer 3.14.33 version.

You should keep rc.syslog enabled though in case of application problems.

You could also install runit from SlackBuilds and run it through inittab and create runscripts to replace the bsdinit service scripts used by Slackware though it will take some work to get dependencies checked and corrected, it can be done very well.

But yes, hibernation and sleep modes help too, otherwise don't worry about it.

For the fastest boot up you could just suspend your system instead of shutting down.

For increasing boot speed without suspending, just disable (chmod -x) scripts in /etc/rc.d that you don't need running. You can also edit 'rc.M' and comment out some of the slower parts or add an '&' after them to background them. You can also rewrite the rc.d scripts in ash, which I have done. This should cut the boot time in half. If that's acceptable try it, I can post my ash scripts, I believe there are also some posted by others if you search this forum.

I'm interested to see your ash init scripts, metaschima.

metaschima · 03-01-2015, 01:09 PM

I've attached the scripts that I converted. Some things in rc.M are commented out, but can be uncommented and they should work. I removed the LUKS code that used arrays in rc.S. I don't even use LUKS, so someone will have to write that without arrays if they need it. Or it can be written in a separate bash script.

Rename the file to .txz instead of .log

It doesn't seem to be attached or linked anymore.

Yes, I noticed that, too. But if you ask, I think you might be able to get hold of a copy of the source. Maybe I still have a copy on m own laptop, but I cannot check it right now
