1 ====== Boot time ======
3 SliTaz boots fast! But most likely you haven't turned super fast boot on yet. To do this, just edit your ///etc/rcS.conf// :
4 <file> FAST_BOOT_X="yes" </file>
6 Remove dbus, hald and slim from the RUN_DAEMONS array. That's all. Note, on some machines, FAST_BOOT_X may not boot properly. However, if Xvesa/Xorg works after you enable this feature, it's safe to leave it on.
8 Now, how do you measure the boot time? SliTaz logs time that rcS scripts take to run in the ///var/log/boot-time// file. In my case, it shows 5 secs.
10 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:
12 <code> # tazpkg get-install pybootchartgui </code>
14 Pybootchartgui will then create a chart automatically in ///var/log//.
16 Now, just edit your //menu.lst// file for grub and add init=/sbin/bootchartd. In my case, it's like this:
18 <file>
19 title slitaz with bootchart
20 root (hd0,8)
21 kernel /boot/vmlinuz-2.6.30.6-slitaz root=/dev/sda9 init=/sbin/bootchartd quiet
22 </file>
24 Here's my boot chart with WPA2 wifi (under 10 secs boot time on a laptop with hard disk). This is out-of-the-box!!!:
