[07:09] <th> 00:00:50 < daja77> btw the laptop is up and running 2.6.13 atm
[07:09] <th> daja77: ping
[07:09] <th> daja77: what's your root= parameter? did you create initramfs stuff?
[07:48] <blindcoder> th: /dev/root? Good question
[07:53] <th> blindcoder: no - udev does not create /dev/root - cause it's not in kernel
[07:53] <th> i guess there is need for some initramfs...
[07:53] <th> but i dont want to believe this
[07:54] <blindcoder> no, there is not!
[07:54] <blindcoder> let me get out my laptop...
[07:57] <blindcoder> there
[07:58] <blindcoder> all you need is a few character devices (console, null, zero and maybe a few others) on your root's /dev directory and then: root=/dev/hda1
[07:58] <blindcoder> or whatever
[07:58] <blindcoder> and init=/sbin/init
[08:01] <blindcoder> but there is absolutely no need for a initial ramdisk
[08:05] <th> hmmmm
[08:06] <th> u think a missing /dev/{console,null,zero} may cause unable to mount root?
[08:08] <th> blindcoder: are you sure that you do not have devfs in kernel? additionally
[08:08] <blindcoder> not unable to mount root
[08:08] <blindcoder> unable to start init
[08:09] <blindcoder> devfs=nomount parameter
[08:09] <blindcoder> not having /dev/console will cause init to fail with "unable to open initial console"
[08:10] <th> that's not fatal
[08:10] <th> and hence not the problem here.
[08:10] <blindcoder> it is here
[08:10] <th> k
[08:10] <blindcoder> because then I get a kernel error: unable to start init
[08:10] <th> but i get unable to mount root
[08:10] <blindcoder> hmm
[08:10] <th> i dont get this if i have devfs still enabled
[08:10] <blindcoder> what's your root= parameter?
[08:10] <th> try disabling in kernel
[08:10] <th> /dev/sda2
[08:11] <blindcoder> sounds fine to me
[08:11] <th> (kernel naming scheme)
[08:11] <th> kernel should convert this to major/minor numbefrs
[08:11] <blindcoder> try the kernel option "verbose" and look for error messages
[08:12] <th> verbose. hmm
[08:12] <th> i did not see any more output in kernel source... let's see
[08:13] <blindcoder> or was it debug? no idea, but quiet is the opposite :)
[08:18] <th> no additional output
[08:18] <th> would be cool if you could try to disable devfs somewhen
[08:18] <th> (or just update to 2.6.13) ;)
[08:20] <th> hmmm where is that maj/min number detection code.....
[08:20] <blindcoder> in do_mount.c IIRC
[08:21] <blindcoder> at least you should be able to trace it from there
[08:21] <blindcoder> well, stupid question, but do you have the scsi modules necessary in the kernel?
[08:23] <th> yes
[08:23] <th> i triple-checked that
[08:24] <th> i've two identical but differing in devfs kernels
[08:26] <th> oh cool i can give maj:min as option
[08:26] <th>         if (sscanf(name, "%u:%u", &maj, &min) == 2) {
[08:26] <th>             res = MKDEV(maj, min);
[08:26] <th> ...
[08:31] <th> uhh i guess the easiest is to give major and minor numbers :-/

[08:36] <netrunner> moin rest :)
[08:37] <th> root=8:2 works
[08:37] <th> that's crazy
[08:38] <th> obviously kernel is unable to translate "sda2" (which is kernel naming scheme) to "8:2"
[08:39] <Pilot> hi all
[08:39] <Pilot> th: afair it could be root=0802 too
[08:40] <th> that's true
[08:40] <th> but it should understand sda2
[08:40] <Pilot> no, kernel has a small device map with hd and fd
[08:41] <th> "hd"?
[08:41] <Pilot> hda, hdb, hdc, hdd
[08:41] <th> a
[08:42] <th> i think kernel should understand names of it's own name-scope
[08:45] <th> so booting without initrd and without initramfs is to complicated for the normal user
[08:45] <th> cause (s)he has to map device-names to major/minor pairs
[08:46] <th> yea - i liked devfs
[08:48] <blindcoder> the first sane thing I heard in days :)
[08:48] <blindcoder> moin netrunner, Pilot 
[08:50] <Pilot> th: kernel actually works with device numbers only, builttin /dev/hd? mapping exists to help 95% of Linux users who boot from IDE
[08:50] <th> Pilot: that's not really true.
[08:51] <Pilot> th: why?
[08:51] <th> Pilot: "sda?" is "kernel nameing scheme" as of udev ;)
[08:52] <th> but perhaps it's only udev suggesting this
[09:04] Nick change: SMP_ -> SMP
[09:05] <SMP> gah
[09:05] <blindcoder> moin SMP
[09:06] <blindcoder> inventing a new language? :)
[09:29] <th> SMP: you have internet?
[09:30] <SMP> I have Internet. lots of Internet.
[09:36] <th> cool
[10:03] <daja77> th: I put devfs back in ...
[10:03] <th> daja77: i've no need for devfs any longer
[10:04] <daja77> well me neither but I needed the machines back working as fast as possible ...
[10:05] <blindcoder> hehe
[10:11] <th> daja77: why does it not work
[10:12] <daja77> the system just hang without devfs
[10:12] <blindcoder> oh no
[10:12] <blindcoder> new SDL version
[10:12] <daja77> the userland on this machine doesn't even know about udev
[10:12] <blindcoder> SDL_OPENGLBLIT is officially obsolete

[14:00] <th> which did not apply and did not build after fixing the patch. i sent you the results iirc
[14:00] <daja77> erh no
[14:00] <th> sure?
[14:00] <th> at least it did not work out
[14:01] <daja77> I believe you, just don't remember any message
[14:01] <daja77> anyway that would still be too old
[14:15] <th> so if you have any time for another try with 2.6.12 or 2.6.13 .. i promise to send the results
[14:30] <blindcoder> shpchp?
[14:30] <blindcoder> never seen that
[14:30] <daja77> that's the problem ^^
[14:31] <blindcoder> never seen a complaint about it either
[14:40] <th> so it's working fine.
[14:40] <th> we should have more of such stuff
[14:42] <daja77> this shows up on my laptop everytime perhaps it depends on the test hardware
[14:43] <daja77> it shows upp in qemu too

[16:48] Nick change: menomc -> mnemoc

[16:50] <praenti> the problem are * and . because they need an excape character before for sed
[16:51] <praenti> forget it. i had a better idea
[16:51] <praenti> s/had/have/
[16:52] <th> . matches any character so using it for . shouldnt be a problem
[16:52] <th> and * can be matched by . as well
[16:52] <daja77> hi praenti btw
[16:53] <praenti> hi daja77 
[16:54] <praenti> th: the better idea is to use another line in the file which begins with "# Ab hier"
[16:54] <praenti> that works but not with \n for newline
[16:56] <praenti> % echo foobar | sed -e 's/bar/\nbar/' results in "foonbar"

[17:04] <praenti> blindcoder: right. can you explain me why this does waht i want?
[17:04] <blindcoder> praenti: it is supposed to ;)
[17:05] <blindcoder> SMP: that's what xine usually does on me
[17:05] <blindcoder> SMP: I've since switched to the sdl output method which works
[17:05] <praenti> but what is the difference between a , and a /
[17:05] <daja77> that's what the kernel did today >_<
[17:06] <blindcoder> praenti: no idea, I've been using , for ages because I was sick of escaping / :)
[17:06] <netrunner> praenti: the / is a bit longer
[17:06] Action: praenti a little bit confused
[17:06] <blindcoder> FWIW:
[17:06] <blindcoder> blindcoder@fuzzy:~$ echo foobar | sed -e 's/bar/\nbar/'
[17:06] <blindcoder> foo
[17:06] <blindcoder> bar
[17:06] <blindcoder> copy and pasted from your line above
[17:08] <blindcoder> I blame your shell
[17:08] <praenti> yes but only on this ubuntu system. on a suse linux 7.x not. the result there "foonbar" *argl*
[17:09] <daja77> *sigh*
[17:09] Action: praenti doesn't understand reality anymore. what the hell is going on...
[17:09] <daja77> you use ubuntu :p
[17:10] <praenti> daja77: only partly
[17:10] <praenti> because i hate debian and s.th. a rock is not available
[17:10] <praenti> s/th/t/
[17:11] <daja77> your typos will teach you to use patterns ;)
[17:11] <blindcoder> hehe
[17:11] <praenti> :-))
[17:11] <blindcoder> praenti: reality doesn't make sense, live with it
[17:14] <praenti> hmm. is a patched sed command. SuSE has left a short note at the end of the man-page
[17:15] <praenti> bla supports \<newline> sequence in all regexp bla
[17:15] <praenti> bla the \ is stripped an <newline> is kept bla
[17:16] <SMP> that doesn't seem to apply to the \n case
[17:17] reinaldo (n=reinaldo@pc-62-24-104-200.cm.vtr.net) left irc: "Leaving"
[17:17] <praenti> SMP: looks like, yes
[17:23] <praenti> using a \ and go into a newlline works. terrible suse sed
[17:46] Action: praenti now understands partly the sed reality
[17:47] <praenti> it is working with real newlines in the script and \\ at the end of each line :-)
[17:49] <SMP> sed reality is a sad reality ...
[17:49] <praenti> thx to all for brainstorming and working solutions on other distris than suse
[17:50] <praenti> SMP: full ack!
[17:50] <praenti> cya
[17:50] Action: praenti afk
[17:50] praenti (n=michael@paulaner.obster.org) left irc: "leaving"
[23:11] netrunner (n=andreas@p549819AB.dip0.t-ipconnect.de) left irc: "shutdown"
[23:23] netrunner (n=andreas@p549825CC.dip0.t-ipconnect.de) joined #rocklinux.
[23:26] kasc (i=kasc@dsl-082-083-131-142.arcor-ip.net) got netsplit.
[23:27] kasc (i=kasc@dsl-082-083-131-142.arcor-ip.net) returned to #rocklinux.
