<bennabiy>
workingcats, don't see why not. the image should just be a squashfs compressed image.
14:23
<workingcats>
bennabiy, great, ty
14:23
<bennabiy>
worth a try at least
14:25
<workingcats>
well i was most concerned about ltsp-build-image making some magic when constructing the image that shouldnt be in the chroot
14:26
oh actually i can just try it cant i.. make a new image, desquash it, compare
14:26
<bennabiy>
yes
14:27
should be able to do a mount -t squashfs -o loop
14:29
worked for me :)
14:30
mounts read only

Just set the wired nic to 192.168.67.1 as the wiki says

18:09
<vagrantc>
init?
18:09
<gbaman>
in the initrd.img-3.10-3-rpi file
18:09
<vagrantc>
does the shell support those read parameters?
18:10
<gbaman>
thats what I dont know..
18:10
<vagrantc>
it's probably busybox shell, or klibc sh

<vagrantc>
add break=init to your boot parameters, and it should dump you to a shell to experiment with
18:11
thouh probably want to put it as a hook rather than mangling init itself
18:11
<gbaman>
ooo
18:11

Nice. Now, can you run the same commands on a client, on a localxterm?
19:10
!localxterm

<ltsp`>
localxterm: Any applications that you launch on a thin client actually runs on the server, not on the client itself. If you want to open a program on the client locally, you can type 'ltsp-localapps <program>' in a run dialog or in a terminal. For example, 'ltsp-localapps xterm' to open a terminal running on the client.
19:11

(on your server, you're up to date with the latest stable kernel/xorg, and they see your graphics card fine)
