Boot configuration

I am running:

Distro: Mixed Debian unstable/experimental

Desktop:Enlightenment, running primarily GNOME apps for consistency, FinalE theme edited to use Vera fonts, maximize keybindings added.

Kernel: 2.6.4-ck2 (Con Kolivas patches mostly for reiser4 and supermount)

Hardware: PII-450 w/ 512 MB RAM and Nvidia TNT2 graphics card, 40GB WD HDD on a Ultra100TX2 controller).

Customizations: Pieces of GNOME 2.6 from experimental thrown in with symlinks to preserve compatibility, devfs, graphical GDM with hacked theme to eradicate useless language menu, running Zsh with custom prompt, changed root prompt colors to red, local debian repository tree for custom packages, custom iptables script, and some more.

Usage: Use Linux exclusively

Boot config: Single boot, no Windows, spare empty partition just in case I need it and for backup purposes when I nuke my XFS filesystem and replace it with Reiser4.

My house is 100% Apple, and I get to be sysadmin by default (ipchains isn't my mother's thing). I have 2 portables (My new toy and my old iBook), my stepfather has a desktop G4, my brother a desktop G3, and we gave my mother my old Centris 650. All of these Macintoshes share a cable modem via the spoofer....

Distro: Debian 3.0 (Woody)

Desktop Environment/Desktop customizations: On a server? Muahahaha no!

Browser: See above

Kernel Version:2.4.26

Hardware you are running it on (CPU, RAM, GPU, and disk capacity)(optional): Power Mac 6300/120

Other customizations/non standard configurations: Pretty stock system

Amount of usage: My brother + me = internet whores. I set the server up ages ago and essentially haven't needed to touch it since. (Unlike some other OSes, Linux doesn't get bored and cause problems when left to it's own devices)

Boot configuration: Linux

Posted: **2004-05-01 10:40pm**

Distribution: Fedora Core 1. I'll be moving to FC2 when it comes out -- and my university has a nice local mirror.
DE: XFCE 4. I may go to KDE 3.2 or GNOME 2.6 when FC2 comes out. Maybe.
Browser: Mozilla 1.6 at the moment. I'm too lazy to find a Firefox RPM.
Kernel: 2.4.22-2188.nptl (some funky Fedora kernel with a bunch of backported fixes and the NPTL).
Hardware: Compaq Armada M700 laptop. P3M/650, 384MB SDRAM, ATI Rage-M 8MB and 10GB HD.
Boot: Standard GRUB loader with one option.

I use my laptop quite often.

Ok, my main box...

Distro: Mandrake Cooker (post 10.0)
Desktop Environment: XFce 4
Desktop customizations: Not much, change GTK+2 themes periodically when the mood hits me.
Browser: Mozilla 1.7
Kernel Version: 2.6.3
Hardware you are running it on (CPU, RAM, GPU, and disk capacity): Athlon XP 2000+, 768 MB RAM, GeForce3 Ti200, 200 gigs total of hard drive
Amount of usage: Daily, mostly in the evenigs
Boot configuration: Space for 11 operating systems available (although getting them to peacefully coexist is a pain). Windows is currently uninstalled thanks to a purely accidental 'rm -rf'-ing of /mnt/windows.
OS list: FreeDOS, ReactOS, Windows 98 Original, Windows 2000 (all four got wiped out, unfortunately), Mandrake Cooker, Slackware 9.1, Gentoo, *BSD (haven't installed it yet), Plan 9 from Bell Labs, SkyOS.

And my laptop.

Distro: Mandrake 9.1
Desktop Environment/Desktop customizations: Currently under construction, will be XFce4 when done. Right now I'm using twm with X11R6.7, built from source.
Browser: ELinks (building Mozilla 1.8a from source with MNG patch applied)
Kernel Version
Hardware you are running it on (CPU, RAM, GPU, and disk capacity): 400 MHz Pentium II, 128 MB RAM, S3 Savage, 10 GB hard drive
Other customizations/non standard configurations: Everything. Only the basic elements (kernel, basic libraries) are standard. All other programs have been built from the sources on their project websites...
Amount of usage: My school laptop, used all the time.
Boot configuration: Dual-boot, Linux and Windows 2000 (for course reasons, I still need Windows).

Distro : Red Hat 9
Desktop Environment/Desktop customizations : standered GNOME
Browser : Mozilla
Kernel Version : 2.4
Hardware you are running it on (CPU, RAM, GPU, and disk capacity)(optional),
2400+ AMD XP, 512 RAM SDRAM , Radeon 9700 Pro, 80GB 7200 RPM Hard disk

Other customizations/non standard configurations. : Nada
Amount of usage : When I need to fix stuff, or whenever I feel an urge to play around
Boot configuration: GRUB with Windows as default.

Oh I forgot to say I use GRUB and my browser is Firefox. Oh, and I have NPTL installed.

Crayz, if you are building everything from scratch on top of Mandrake, you might as well use Linux from Scratch (download coredistro as the base to build Linux from Scratch from, then use the bootdisk to nuke the coredistro stuff and replace it with LFS, or use Mandrake to build LFS). I used ALFS a few years ago, with edited scripts to allow installation from single partition (had 1GB hard drive). You could build stuff on coredistro directly, but it's not optimized (most importantly, libc isn't optimized), it uses a BSD init, and it's missing man pages and libraries, and compilation tends to break. Also, packages are dated.

Well, I'm using Mandrake 9.1 since it works with my PC cards. The latest and greatest, at least in the kernel world, didn't seem to help. I still use RPMs occasionally anyway.

Dude, nice. Tell me more about your HDD & Controller and how you figured yourself for -a512 for your reads, please.

Oh, BTW for everyone else, I forgot (Thanks for reminding me Pu*):

 "idex=ata66"           : informs the interface that it has an 80c cable
                          for chipsets that are ATA-66 capable, but the
                          ability to bit test for detection is currently
                          unknown.

(/usr/src/[kernel directory]/Documentation/ide.txt) option when googling, after hdparm -X didn't have any effect (this seems to make the biggest difference, if the -a is left to default). The -a option I adjusted (explicitly set it to the recommended value), then when I upgraded to 2.6.4 the reads slowed down, since the kernel apparently interprets the value differently, so I experimented beyond recommended values... 512 seems to be optimal for max hdparm reads (may not be for actual usage, so lowered to 256 just in case... then again, caching in ram may make this irrelavant, since -a adjusts readahead, so sustained throughput may not be as high.

I just dded 200 MB from a reiser4 disk image to the ramdisk, and it took 28.5 seconds, so it's about 7 MB/s sustained... then again, it was 2 seconds for 40MB, and I'm doubtful anyone would transfer more than that on a regular basis. I'm also not sure if tmpfs sends things to swap, which would really screw up the 200MB test(EDIT: tried by dding to /dev/null, 11 seconds, 18MB/s, so yes, it probably was an issue with swap. Lowering -a to 72 doesn't make much difference when transfering small quantities from disk image to ramdisk though however, so I just switched back to 512. )
