# Note:         Please send me an email if you enhanced this document
# System:       Ubuntu Linux and Debian GNU/Linux
# Version:      0.1.1
# Date:         2009-06-23

# purpose:
# I build a lot of different linux systems, some just need fast bootup
# like multimedia devices, easy internet devices, netbooks et cetera.
# one of the requirements is maintainability and stability.
# I don't get maintainability by recompiling my own software, so that is
# not an option. What is an option is to tweak all the configuration
# systems I can find, test them for stability and use them.

# major issues:
# the udev process takes an awful lot of time it just stays for more then
# 7 seconds in the "Waiting for /dev to be fully populated" state probably
# caused by udevadm settle. We need to tune udev to become way faster and
# keep the solution easy to use and maintainable.

# rectification:
# I had a chat with the debian udev maintainer and he said the issue is not with udev.
# The udev process, calls modprobe that show a lot of unint.sleep and its waiting for
# something. modprobe interacts with the kernel modules so the issue is with the kernel
# not udev. It's probably waiting for the kernel initializing the hardware. So we may
# need a better kernel or module loading process? Any ideas?

# I use grub2 and it has no behavior like hiddenmenu, you can see three flashes
# during boot before it comes to the steady "loading system" state.

# sometimes my asus eeepc 901 just won't turn off at the last stages of halt.
# I got the feeling that some hardware (audio, network) is not correctly
# deinitialized and makes the shutdown process hang. SySRq doesn't react in this
# stage anymore so the kernel is probably down already.

# result:
# my boot process is around 13 seconds and 7 á 8 of them are caused by udev.

[Timo Tamminen]

Olemme suomenkielisellä foorumilla, joten voisitko vaihtaa otsikoksi jonkin suomenkielisen lauseen. Kiitos.

[nm]

pääpiirteittäin jotenkin selvää tekstiä mullekin, mutta jaksasko joku vääntää tän kokonaan suomeksi

Aika vanhaa juttua, eli ei välttämättä enää pidä kaikilta osin paikkaansa.

SSD-levy koneeseen niin säästyy aikaa ylimääräiseltä virittelyltä.

[Postimies]

Mikä tuossa on epäselvää? Suurimmaksi osaksi komentoja käynnistysnopeuden
lisäämiseksi. Hitaammassa koneessa kernelin kääntäminen ja initrd:stä luopuminen
voi tuoda hieman lisää nopeutta. Näin udev:in ei tarvitse odotella kernelin moduleiden
latautumista jos ne tärkeimmät on käännetty mukaan. Minulla oli aikoinaan EeeBox koneessa
LUbuntu ja Gentoo. Käynnistysnopeudessa ei juuri ollut eroa, vaikka hidas levy ja 1,6 GHz
prosu. Virittelyn tuoma etu voi olla vain muutama sekuntti.

[qwertyy]

Täysin Asus EEE 901 spesifistinen artikkeli. Valtaosa ohjeista ei ole enää millään lailla ajankohtaisia. Lisäksi suurin osa nopeutuksista liittyy kustomoituun kerneliin ja muutamien palveluiden karsimiseen sen myötä.

[Postimies]

Täysin Asus EEE 901 spesifistinen artikkeli. Valtaosa ohjeista ei ole enää millään lailla ajankohtaisia. Lisäksi suurin osa nopeutuksista liittyy kustomoituun kerneliin ja muutamien palveluiden karsimiseen sen myötä.

Ei kernelin kääntäminen kovin paha ole jos löytää laitteelle valmiin config-tiedoston. Menee tyyliin make oldconfig && make.
Hitaalla koneella käännös kyllä kestää, mutta kun turhat on pois yleensä aika nopeasti. Vaikka 15-30 min.
Vaatii tietty gcc, make, .. riippuvuudet. Kernelit ovat paisuneet kovasti. Tilaa pitää olla reilu giga - jos kääntää
ram-levyllä menee hetkessä.

[qwertyy]

Juu no sitä en varsinaisesti tarkoittanutkaan. Lähinnä sitä että tuo ohje ei ylipäätään ole kovin ajankohtainen enää ja osa vinkeistä ei suoranaisesti taida enää edes toimia. Tuossahan ei edes käännetä kerneliä, vaan sekin on erillinen jonkin kustomoima kernelipaketti, joka ladataan valmiina koneelle. Villi veikkaus että kyseistä ydintä ei edes enää löydy mistään.
