2 days of tweaking for a faster boot time

Crooksey · 2009-04-04 08:04:42

1. It took you two days?
2. I think maybe you are using the wrong distro.

Duologic · 2009-04-04 10:42:49

If you've read thru the topic, you know it isn't just about the two days.

Why would this be the wrong distro for me?

Imho: http://bbs.archlinux.org/viewtopic.php?id=69086 is just better

Duologic · 2009-04-05 14:28:32

I could have a lot of arguments against netbooks, but I just think they suck. Some cheap marketing stuff to get more money out of the masses.

(no offence to you or a tweaker)

Bah, I disagree.
I got a desktop pc used for homing, and I just use my acer aspire 9''(paid 189 euros) at university. It's really comfortable.

How did you manage to get it for 189 euros ? I'd jump on that train any time
I can't see netbooks here for less than ~450 euros....that's just way too much

I just take my 15" Dell Inspiron anywhere, comfertable and a decent screen size. I gues I'm too much a anti-expensive-gadget guy. If these netbooks where sold by there value 'about 99 euros', then I would buy me one too. I hear you think why 99 ? Well, we all know OLPC project, almost the same out-of-date hardware in that as in de netbooks.

but this goes too much off topic.

In italy you can get an eeepc 701 with 99 euros

Duologic · 2009-04-05 18:16:22

Ok, but the 7" is still to small, I was talking about 9"+ where you can have a nice resolution on. We should really open a new topic.

What are you talking about? The specs of most recent netbooks knock the socks off the crappy XO Laptop. They're different products for different markets, you can't really compare them.

Lol so my acer aspire bought with 189 euros would be perfect for you. 9'', 1024x600, Atom 1.6 Ghz, 12 SSD Gb, and a 1.5 gb ram memory. Archlinux makes it waaay fast

Wow, this is good stuff. I'm glad I found that wiki page ... Not sure what my before would be (fairly new install, so I guess there really can't be one), but the 'after' is certainly decent.

Oddly enough, it seems bootchart is timing the whole way until kde is up. As good as things already are; though, I'm thinking things could still be better. Any ideas for me?

You can take some stuff like LVM, Cryptab and RAID out the rc.sysinit if you don't use it, but that wouldn't be so significant.

If network is not necessary, do the network after the boot with a network manager. DHCP takes some time. Or use static addressing.

Run kdm from inittab, not as a deamon.

Meh, I read somewhere that your boot time may decrease using squashfs and unionfs (or aufs now I think) and possibly some performance, but I forget and I am no expert on it yet. It was in the Gentoo forums. Other than that, can't think of anything else to decrease my boot time, but I'd be very please to get it down to 9 seconds.

Yeah, I don't think any distro is the wrong distro to use. What matter is your attitude. If you start with Ubuntu and you want a faster boot time, you're going to work hard to get a faster boot time whether it means trying a different init system, trying readahead, editing your init, compiling your kernel, some of us use static /dev, and so on. Arch won't stop you, Ubuntu won't stop you, Gentoo won't stop you, and so on.

By the way, pretty proud of my boot time, hehe. This is on a Intel Celeron M 440 @ 1.86GHz, with 1.5G of RAM (not bad, memory is cheap), and my hard drive is a FUJITSU 5400 rpm (so it's not an SSD or a desktop with 7200 rpm). Very fast boot time, beyond awesome performance, and that's without cutting featuers (other than dynamicness and portability).

I think the most fun thing to work with though is the kernel. I am not into just compiling the kernel or editing .config, but even the coding. Nothing advance though. I've been reading Understanding the Linux Kernel a bit, learned how to write modules here, there is an online copy on how to write device drivers here. There is also an online copy of Understanding the Linux Kernel in Google Books, but some pages are missing and it throws you off. That's how I started reading it in the first place.

To me, bringing down my boot time wasn't just about the time I will save by getting it down, but just for the sake of knowing at first. Since it is down so low though, I actually turn off my computer and save electricity though which is a good thing. The time spent getting my boot time down and learning more mostly about what happens when your computer boots, learning about the Linux kernel, understanding device managers such as udev or dev9 or deprecated devfs or how to even have static /dev (I used to think static /dev was just like a package you could download), and so on is totally worth it.

Very interesting. Started to play with your 2nd idea: Commenting stuff in /etc/inittab: lesser agetty's. Looks easy but it gave a surprice: switch to another terminal and wanted back to X with crtl+alt+F7 did no longer work. So for beginners (like me) it's useful to note: your X virtual terminal moves to the first empty terminal you have. In my case crtl+alt+F5.
Since everyone is used to nr. 7, i need to tell X to use the 7th terminal and after some googling changed /etc/X11/xinit/xserverrc (added the vt07) into: exec usr/bin/X -nolisten tcp vt07

Duologic · 2010-01-02 12:09:31

That X uses the last available vt is normal behavior to me and most of the linux community. Try opening a second X with 'xinit -- :1' and it will open in the next vt.

Awesome topic. With some minor fiddling (removing raid/LVM) I strand at 22s.

When i look at bootchart however, I see a LOT more in my boot than other users. I'm not asking for a "copy pasta" solution (otherwise I wouldn't be using arch) but any quick thoughts where to start cutting?

you could try to disable the ntfs partition from being auto mounted on boot (unless you specificaly need to access it)

SantaSCSI · 2010-01-13 18:32:40

Since I use dual boot and place all my documents/images/... on a "unidata" ntfs partition, it's not possible to do so .

leberyo · 2010-01-20 21:39:44

Hi quick question. I followed the direction to set the UTF, with;
stat_busy "Setting Consoles to UTF-8 mode"
# UTF-8 consoles are default since 2.6.24 kernel
# this code is needed not only for older kernels,
# but also when user has set vt.default_utf8=0 but LOCALE is *.UTF-8.
for i in $(/usr/bin/seq 0 63); do
usr/bin/kbd_mode -u < /dev/vc/${i}
printf "\e%%G" > /dev/vc/${i}

Now on boot up it gives me "No such file or directory /dev/vc....
about maybe a half dozen lines one after the other. Any idea?

Also, for the keyboard map, I see that you set it to be-latin1, which I assume to be Belgium-Latin1. What do US users have to set this to? US-latin1?

Thx

Why don't we just copy/paste all of rc.conf into rc.sysinit, so that rc.conf doesn't have to be sourced during boot? Especially after you hardcode all the HWCLOCK/LOCALE stuff, it's basically just the modules and daemon arrays anyway.

leberyo · 2010-01-21 17:32:52

I still get a "No such file or directory" because of these two lines in rc.sysinit

usr/bin/kbd_mode -u < /dev/vc/${i}
printf "\e%%G" > /dev/vc/${i}

Anybody know the correct useage?
