 Posted: Sun Oct 31, 2004 5:01 pm Post subject: Need some guidance in setting up a new system |
 |
|
Hey everyone...
I'm preparing to setup a new linux system, but this time I want to set it up really good right from the start.
For example... I'd like to use reiser4, udev, NPTL, and whatever else I can to make a really fast system. I'm planning on using the latest GCC version (at least 3.4) and ~x86 packages.
How can I do this right from the start. The livecds from gentoo don't allow this, afaik.
Any advice?
Also, what would you consider for a nicely tuned, but safe CFLAGS setting?
Thanks guys....

I used a reiser4-enabled LiveCD to install Reiser4 as my root partition filessytem. The one I used is available from: http://lxnay.dnsalias.org/livecd-iso/index.php
You can try putting nptl in your USE flags during install, I tried this but it got confused with linux-headers so I just did it after the installation.
Hope this was of help. |

thanks for the link...
I'll go download that right now...
As for the other options.. one thing I would really like to install from the begining is udev. I don't want to install devfs, and then replace it with udev... I just want to install udev in the first place.... anyone know how?

| Just continue installing like normal until you have emerged the base system (right after "emerge system"), and then follow the udev guide. |

Things to do:
Get a Reiser4 LiveCD. There are at least three on this forum. 
fdisk your disk, and then just:
mkfs.reiser4 /dev/hd##
And mount.
When you've chroot'd into your new environment, do the following:
a. emerge patch (VERY IMPORTANT)
b. emerge -C linux-headers
c. emerge linux26-headers
d. Change the line in /usr/portage/scripts/bootstrap.sh
| Code: | | emerge ${STRAP_EMERGE_OPTS} ${myOS_HEADERS} ${myTEXINFO} ${myGETTEXT} ${myBINUTILS} |
To:
| Code: | | emerge ${STRAP_EMERGE_OPTS} =sys-kernel/linux26-headers-2.6.8.1-r1 ${myTEXINFO} ${myGETTEXT} ${myBINUTILS} |
Then run the script. Make sure 'nptl' is in your USE in make.conf.
DevFSd is still the standard in 2004.2. But to get UDEV, just:
a. emerge -C devfsd
b. emerge udev
c. Don't build /dev support into the kernel.
It'll be like DevFSd was never installed.
For CFLAGS, do whichever you want. Ones I use are:
| Code: | | CFLAGS="-march=athlon-xp -O2 -pipe -fomit-frame-pointer -ffast-math" |
-O3 is a waste of time and you'll notice no speed enhancement from it. And actually, -O3 has been shown to be significantly slower on Intel systems, so don't use it anyways. -ffast-math, to the best of my knowledge, gives good latency on graphics-driven programs. So if you're going to use XOrg, use -ffast-math.
For ~x86, just do: ACCEPT_KEYWORDS="~x86" right in your make.conf.
And finally, to get GCC3.4, do the following.
| Code: | rm -r /etc/make.profile
ln -sf /usr/portage/profiles/gcc34-x86-2004.2 /etc/make.profile |
This is what I've done to get a fast, stable system. Currently on two weeks uptime doing many, many things.
EDIT: Fix stupid typo.

should probably be:
ln -sf /usr/portage/profiles/gcc34-x86-2004.2 /etc/make.profile |

Err, right.

There's a thread somewhere about "stage 1 with nptl - the developer's method" or something - that's very similar to what HydroSan posted though.
HydroSan: I heard -ffast-math was a bit on the less-than-stable side - works okay for you? |

Week and a half uptime of:
a) Playing UT at least three hours a day.
b) Using GNOME, GIMP, Firefox, XINE, and Crossover Office.
c) Syncing and updating software.
No problems at all.

Out of curiosity, what kernel are you running with all of this? |
