Boot time

SliTaz boots fast!! But most likely you haven't turned super fast boot on yet. To do this, edit your /etc/rcS.conf :

 FAST_BOOT_X="yes" 

That's all. Now, how do you measure the boot time? SliTaz logs time that rcS scripts take to run in /var/log/boot-time file. In my case, it shows 5 secs.

But, how do you graph your full boot process (including the kernel-boot time)? Its quite easy on SliTaz. Just do and install the following:

 tazpkg get-install pybootchartgui 

Pybootchart will create a chart automatically in /var/log.

Now just edit your menu.lst file for grub and add init=/sbin/bootchartd. In my case, it like this:

 
title slitaz with bootchart
root (hd0,8)
kernel /boot/vmlinuz-2.6.30.6-slitaz root=/dev/sda9 init=/sbin/bootchartd quiet

On asus-eee ssd system, 6 sec boot time + 2 sec for wifi has been observed. Here's my boot chart with WPA2 wifi (under 10 secs boot time on laptop with harddisk):
