<vagrantc_>
ogra: i just talked with joeyh about using debconf-apt-progress in the ltsp-client-builder udeb to get a better progress bar ... did you remember exploring that?
07:03
<ogra>
no, since when does it exist ?
07:03
<vagrantc_>
not sure.
07:04
looks promising... though with all the file descriptor redirections, this stuff gets tricky
07:05
<ogra>
yeah
07:06
the prob is that we run two different subprocesses in ltsp-client-builder, one for ltsp-build-client and one for ltsp-update-images
07:06
i never managed to make both work
07:07
beyond that in-target already steals the descriptors
07:07
<vagrantc_>
showed me some ways to stop and resume progress ... i.e. start here at 25%, stop at 50%, do stuff, start back up at 50% ...
07:09
<ogra>
right, but it requires that you capture the info from the different subprocesses somehow
07:09
showing a progressbar was never my problem :)
07:09
are you in europe btw ?
07:10
<vagrantc_>
ogra: yeah, extremadura :)
07:10* ogra just remembered there is debconf next week
07:10
<vagrantc_>
debcamp this week
07:10
<ogra>
ah, i was already wondering why you work at that TOD :)
07:10
<vagrantc_>
the highlight of my day, yesterday was unloading a truck full of debian-branded wine
07:10
TOD?
07:10
<ogra>
hehe
07:10
time of day
07:11
<vagrantc_>
it's kind of silly that spain is still at +2 ... solar high noon is around 2pm or so...
07:12
speaking of which ... lunch!
07:12
<ogra>
not only spain :)

helo all, do you know what might be a reason of "acpi: Invalid PBLK length" during boot of thin client? it stops booting on console login screen... thanx for help
07:58DaZ- has quit IRC
08:02
<ogra>
szczym, what distro/release ?
08:02
sounds like a kernel problem
08:02
<szczym>
9.04
08:04
<ogra>
probably https://bugs.launchpad.net/ubuntu/+source/linux/+bug/197267
08:04
there are some links to the ACPI debugging page
08:04
<szczym>
i installed it on other server computer and inserted HD into new server. would it be a problem ?
08:05
<ogra>
in ltsp you set kernel options in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
08:05
<szczym>
but its booting fine into gnome and all works on on server
08:05
<ogra>
you said you see the message on a thin client
08:05
<szczym>
yes, i see on client
08:06
<ogra>
so ut doesnt matter if your server works fine, the thin client is different hardware and you are seeing a hardware problem with the kernel
08:07* ogra would start with this suggestion: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/197267/comments/3
08:08
<szczym>
thanx for help ogra, i will tray that

question
08:37
<vagrantc_>
!question
08:37
<ltspbot>
vagrantc_: "question" is if you have a question about ltsp, please go ahead and ask it, and people will respond if they can. please also mention the linux distro and release you're using. :)
08:37
<GGD>
if i put ltsp on a particular os does it automatically netboot that OS?
08:41
does that make sense?
08:41
<vagrantc_>
ltsp5 will typically build an LTSP environment that's built using the host OS.
08:41
<GGD>
oh ok
08:49alkisg has quit IRC
08:49bobby_C has joined #ltsp
08:51
<ogra>
vagrantc_, oh, since when does ltsp-server depend on debconf-utils ?
08:54
<vagrantc_>
ogra: a good long while ago
08:54
probably added it to support preseeding or some such
08:55
ogra: seems like all the way back to 2005
08:56
<ogra>
wow, i wasnt aware
08:56
<vagrantc_>
ogra: part of mdz's merging pere's patches
08:56
<ogra>
yeah
09:01
hmm, five lines changed, ltsp-build-client --arch armel is running ;)
09:01* ogra wonders if it gets through until kernel selection
09:06
<ogra>
vagrantc_, do you have any idea if $DEBOOTSTRAPOPTIONS needs to be available in the second stage if building for --foreign ?
09:06
hrm "W: Failure while installing base packages. This will be re-attempted up to five times ..."
09:07
would be nice if it could be a bit more verbose
09:07
especially since debootstrap works fine just building a chroot
09:08
funny and it just moves on then
09:08
<vagrantc_>
ogra: i thought --foreign actually wrote a script that should hopefully pass those options on...
09:08
but i don't really know ...
09:08
<ogra>
ah, good, then i did it right
09:09
<vagrantc_>
i sure hope you don't have to repeat all the same options...
09:09
<ogra>
heh
09:09
yeah, that would be silly
09:12
gah
09:13
stgraber, we need to adjust ltsp-build-client for new upstart
09:13
/opt/ltsp/armel/etc/event.d/tty[2-6] are gone now
09:16* vagrantc_ is reconsidering doing any whitelisting at all
09:18
<ogra>
in karmic+1 ubuntu can use upstart jobs for everything ... then it wont be needed anymore
09:19
we just switched to upstart 0.6
09:20
and given that we aim for 10sec bootime in karmic (including the dropping of usplash) fiddling with the bootprocess should be obsolete anyway

stgraber, so essentially karmic should support these http://www.blogcdn.com/www.engadget.com/media/2009/01/pegatron-free-029.jpg once they are on the market :)
13:58
given that the netbooks are supposed to cost below $200 i would expect the nettops to be around $100 ...
13:59
<NeonLicht>
what are the nettops?
14:01
mmmhhhhh... small lowpower desktops w/o HDD,etc (ala netbook), maybe?
14:13
<stgraber>
ogra: do you have real video driver now ?
14:13
last I heard it was some FB driver without real acceleration
14:43
<ogra>
there will be one, not sure it will be open, but it will be in ubuntu (worst case like nvidia)
14:50
<stgraber>
good

<Kati_Zwisch>
hi
16:31
i have this problem here
16:31
http://pastebin.com/m7b7a5338
16:34
<alkisg>
Kati_Zwisch: can you try appending the following in a new line at the end of /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default?
16:34
IPAPPEND 3
16:35
...and reboot the client...
16:37
<Kati_Zwisch>
is the kernel bug?
16:38
<alkisg>
Kati_Zwisch: it may be, but it may also be something else. Did you try what I said?
16:39sene has quit IRC
16:39
<Kati_Zwisch>
is it a kernel bug?
16:39
sorry
16:39
<alkisg>
Kati_Zwisch: also, does the client have 1 NIC or does it have 2 NICs?
16:42
<Kati_Zwisch>
just a moment, I'll try it

<vagrantc>
alkisg: hey, i've got support for ipappend in the latest ltsp :)
16:54
<alkisg>
vagrantc: is that commited upstream?
16:54
<vagrantc>
alkisg: yeah
16:54
<alkisg>
cool :)
16:54
<vagrantc>
alkisg: that's what i meant by latest ltsp
16:55
uploaded to debian, of course :)
16:55
also supports pxe menus, and memtest86*
16:55
<alkisg>
Yeah but I'm a little fuzzy on which part of the initramfs is common between debian and ubuntu, what is ltsp upstream and what initramfs upstream etc
16:55
<vagrantc>
i pretty much have been meaning to get those features in since 2007
16:56
well, when debian pulls a new upstream version, it'll have support for it too
16:56
er, ubuntu pulls ...
16:57
<alkisg>
Did the creation of pxelinux.cfg/default changed? I.e. the PXELINUX_CMDLINE variable in ltsp-kernel.conf?
16:57
<vagrantc>
yeah.
16:57
killed PXELINUX_CMDLINE
16:57
maybe
16:57* alkisg needs to read up on this :)
16:58
<vagrantc>
it has options to append arbitrary files to the configs ... but the defaults essentially work the same.
16:59
still plenty of room for improvement, but most of the cases i've heard of that people have been fighting with should be more easily dealt with
16:59
<alkisg>
I think Ubuntu will use udhcpc for Karmic, though...
16:59
<vagrantc>
shouldn't change anything
16:59
this is just the pxelinux boot menu
17:00
<alkisg>
Well, the back-end handling would be different (i.e. ip=xxx parameter)
17:00* vagrantc finds it ironic to hear talk of udhcp again
17:02* vagrantc has uploaded new versions of all things related to ltsp to debian in the last two days
17:02
<alkisg>
I don't know how bug-free udhcpc is, but I'm sure it has fewer bugs than ipconfig!
17:03
vagrantc: what do I need to install to try them out? sid or experimental?
17:06Kati_Zwisch has left #ltsp
17:11
<vagrantc>
alkisg: it's in sid, although you can probably install lenny with just the ltsp-relevent packages.
17:12
i'm testing it now
17:20* vagrantc notices that debian excludes cron by default
17:21
<vagrantc>
so all stgraber's new cron code won't work
17:24
well, current ltsp seems to work in debian lenny/stable
17:24
at least with initial testing...
17:25
with the bonus that sound still works ...
17:25* vagrantc can't figure out why pulseaudio doesn't start
17:40
<Ahmuck-Jr_>
pulseaudo doesn't start where?
17:40
<vagrantc>
on debian testing/squeeze ...
17:40
works fine on debian stable/lenny
