MyLive, yes, it is.
08:36

<bennabiy>
Is there a script that someone knows of which can back up the settings in pxeconfig.0/default before ltsp-update-image fires, and then replace it after?
17:21
<workingcats>
bennabiy, cp pxeconfig.0/default ~/pxeconfig.bak && ltsp-update-image && mv ~/pxeconfig.bak pxeconfig.0/default
17:21
:P
17:22
<bennabiy>
No no no. It is not supposed to be simple!
17:22
Where are the #! and the comments,
17:22
variables! I need variables!
17:23
workingcats: Thank you once again
17:23
<workingcats>
^^
17:23
does that really do what you need?
17:23
i was kinda taking the .... ;)
17:23
<bennabiy>
Is there a place where I can actually modify the ltsp-update-image call so that if someone else does the update, and does not know about my script, it will do that?
17:28gbaman has left IRC (gbaman!~gbaman@90.210.248.68, Remote host closed the connection)
17:36
<bennabiy>
I have found different things in documentation which refer to editing files which do not exist on my system eg # Do not edit, see /etc/ltsp/update-kernels.conf instead.
17:37
which is a file that does not exist
17:37
and tells me nothing of what needs to go in the file if I do make it
17:37
<workingcats>
well you could rename the file, then place the oneliner as a shell script there
17:38
just add a line at the beginning #!/usr/bin/env sh
17:38
that should do
17:38
tho its a pretty filthy approach
17:39
<bennabiy>
which would probably break on an update as well, possibly
17:39
<workingcats>
yep
17:39
<bennabiy>
hrm
17:40
<workingcats>
it certainly should break on update to the package owning that file

!update-kernel.conf
18:31
<ltsp>
Error: "update-kernel.conf" is not a valid command.
18:31
<bennabiy>
worth a try...
18:31
!help
18:31
<ltsp>
(help [<plugin>] [<command>]) -- This command gives a useful description of what <command> does. <plugin> is only necessary if the command is in more than one plugin.
18:34
<alkisg>
bennabiy: what do you want to put in pxelinux.0 and keep it there?
18:49
<bennabiy>
video=LVDS-1:d
18:50
<alkisg>
bennabiy: you can put it in update-kernels.conf, or you can put it in 01-mac-address files for only the intel clients, or you can conditionally create a customized xorg.conf for them
18:50
<bennabiy>
How do I put it in update-kernels.conf I cannot find any documentation on that file
18:51
<alkisg>
Which distro/version?
18:51
<bennabiy>
mint 15 server/ubu13.04 client
18:51
MATE Desktop
18:51
<alkisg>
Mint 15 is based on 13.04?
18:51
<bennabiy>
yes
18:52
<alkisg>
So you should have an /opt/ltsp/i386/etc/ltsp/update-kernels.conf file, right?
18:52
With this in it: CMDLINE_LINUX_DEFAULT="init=/sbin/init-ltsp quiet splash plymouth:force-splash vt.handoff=7"
18:53
...change that, then run /usr/share/ltsp/update-kernels in the chroot, and ltsp-update-kernels outside of it
18:53
<bennabiy>
I will check. It seemed like it was telling me the file was supposed to be in my server /etc/ltsp not chroot etc/ltsp
18:53
Where are you getting this documentation / information?
18:54
<alkisg>
Erm, I'm one of the devs that helped there... but unfortunately it's not well structured yet
18:54
It should be more straightforward to change/keep user defined settings
18:54
<bennabiy>
Ahh.
18:55
ok. I found the file
18:56
so in the CMDLINE... entry, do I paste in the whole init= string that I want to be there?
18:57
<alkisg>
No, the nbd vs nfs parts are added to it, based on other variables
18:57
Just append the video=LVDS.... parameter
18:58
<bennabiy>
Ok.
18:58
Why does the kernel update every time I run ltsp-update-image?
18:59
<alkisg>
What kernel? Do you mean pxelinux.0?
18:59
<bennabiy>
the pxelinux.cfg/default file says it only gets overwritten when ltsp-update-kernel gets run
18:59
but I have not run that once
19:00
<alkisg>
ltsp-update-image runs ltsp-update-kernels to ensure the nbd image has the same kernel as the tftp dir
19:00
<bennabiy>
ahh
19:01
That would be good to document
19:01
I am sure I am not the only one who does not know this :)
19:01
<alkisg>
The wiki is editable by anyone :)
19:01
<bennabiy>
I was searching and searching for any type of documentation even for the file update-kernel.conf, but it was not making itself available
19:03
I really appreciate your help.
19:03
<alkisg>
np
19:05
<bennabiy>
one more question
19:05freedomrun has left IRC (freedomrun!~freedomru@unaffiliated/freedomrun, Quit: So long and thanks for all the fish)
19:05
<bennabiy>
is there any hope of having a customizable LDM? more than just changing the background and logo and font color?
19:06
<alkisg>
We plan to drop LDM, and allow any other DM to be used instead (e.g. lightdm)
19:06
<bennabiy>
and still have the ssh ?
19:06
<alkisg>
Yup
19:06
<bennabiy>
when do you expect this to happen?
19:06
and is it possible to do it manually now?
19:07
<alkisg>
In LTSP 6, time frame unknown... maybe in a year or so
19:07
It is, a couple of users have done it, but it's not easy
19:10
<Hyperbyte>
alkisg, you've been back from vacation like what, three hours, and you're already on the LTSP support bandwagon again?
19:11
Man you're productive. I usually need recovery time after weekends, vacations...
19:11
<alkisg>
Hehe, just relaxing from the trip :) Tomorrow I'll start working .so... :(
19:11* Hyperbyte gives alkisg a manly hug
19:13
<bennabiy>
Hyperbyte, are you one of the devs as well?
19:20
<Hyperbyte>
bennabiy, what makes you think that?

Has anyone tried to do LTSP over WAN?

I did get involved a bit more in the LTSP project though, I worked a lot on the www.ltsp.org website
20:10dsugar100 has left IRC (dsugar100!~dsugar@columbia.tresys.com, Quit: dsugar100)
20:22
<bennabiy>
nice
20:23
Any experience with LTSP over WAN with multiple servers confederated together?
20:24
<Hyperbyte>
Never done that.
20:25
<bennabiy>
I have a unique situation where I have people all over the world, which each run local labs, but also travel between the labs.
20:26
We are trying to make a way for the users to travel between labs without too much trouble, and without having to haul a lot of storage around
20:30
<Hyperbyte>
That doesn't sound too hard.
20:31
Depending on the internet connection speed you have at all the places and the size of the files that people work with.
20:35
<bennabiy>
Some files are decent sizes.
20:35
but perhaps for those, they could travel with a little drive
20:37
I guess it would help to have a fat client of sorts, so the image doesnt need to load, or could load the local lab image, and just mount the home directory over the network to the home lab
20:39
<Hyperbyte>
One central file server, where the LTSP fat client image is stored, as well as the home directories
20:39vagrantc has joined IRC (vagrantc!~vagrant@freegeek/vagrantc)
20:39
<Hyperbyte>
On rebuild, the fat client image is synced to all local LTSP servers
20:40
And all LTSP clients mount home directories from the central server and log in via LDAP
20:41brunolambert has left IRC (brunolambert!brunolambe@nat/revolutionlinux/x-vtkqkgfavwrnhiqi, Quit: Leaving.)
20:46
<bennabiy>
Basically, all of our labs are going to have the same programs installed, and then the local servers can choose custom software based on local needs
20:46
anyways, I gotta go for now
20:46
thanks for the help
