<joe_sizlack>
ah, sorry, you still around vagrantc?
00:09
<vagrantc>
little bit
00:09
<joe_sizlack>
is mounted as an aufs overlay on /rofs/. When I update my chroot, /rofs/ gets the new changes but / still has the old stuff
00:09
say I add a printer in /etc/cups in my chroot for instance
00:09
<vagrantc>
reboot
00:10
<joe_sizlack>
ahh
00:10
no way around it?
00:10
<vagrantc>
don't know of one, but that's not saying a lot
00:10
<joe_sizlack>
haha, you were supposed to be the aufs goto man :)
00:10
<vagrantc>
the changes should get reflected automatically, though
00:11
unless they are files that were changed in the tmpfs layer
00:11
this is with NFS or NBD?
00:11
<joe_sizlack>
nfs
00:11
on fat clients
00:12
<vagrantc>
nbd would require a reboot for sure ... nfs *might* be able to get away without it
00:12
<joe_sizlack>
right
00:12
one of the reasons I liked nfs over nbd
00:12
<vagrantc>
joe_sizlack: if some of the modified files are in the /cow, you could try deleting those files from the /cow ... but i'm not even sure that's accessible anymore
00:13
<joe_sizlack>
what does /cow do?
00:14
where does it fall in the scheme of / and it's relationship to /rofs/ I mean
00:14
I can access it
00:14
<vagrantc>
that's where the tmpfs is
00:15
the / dir is an aufs filesystem composed of /rofs and /cow
00:15
the writes go to cow
00:15
<joe_sizlack>
ah
00:15
<vagrantc>
(Copy-On-Write)
00:15
<joe_sizlack>
got it
00:15
well I hope to sort out a way to do this
00:15
<vagrantc>
i suspect cups files get written, as there's ltsp-specific code that updates the printer settings from lts.conf
00:16
<joe_sizlack>
well any conf really
00:16
<vagrantc>
you could run something like puppet on the fatclients to apply changes locally
00:16
but clients would accumulate a bunch of changes over time
00:17
<joe_sizlack>
i'd like to be able to chroot the chroot on the server and make common day to day changes
00:17
without having my guys reboot 'n all
00:18
I just finished my HA ltsp setup
00:18
about to spin it up tonight
00:18
it's gonna be rad
00:22
<vagrantc>
nice
00:24
NFS is a lot more forgiving about reconnects to the server

Ok, here is one for you guys... wifi...
19:28
Raspberrry Pi LTSP via wifi..
19:29
seeing as the pi already has the kernel on the SD card
19:30
Is that even possible alkisg and vagrantc?

<gbaman>
?
20:00
alkisg?
20:23
<alkisg>
!arcfour | echo Hyperbyte:
20:23
<ltsp>
Hyperbyte: arcfour: http://en.wikipedia.org/wiki/RC4 is an SSH cipher which is more than 2 times faster than the default aes128-ctr. To enable it, set LDM_SSHOPTIONS="-o Ciphers=arcfour128".
20:23
<gbaman>
?
20:24
<alkisg>
gbaman: no need to ask specific persons, just mention your questions in the channel, and anyone that has something to say about them will do so...
20:24
<gbaman>
:)
20:24
<alkisg>
Personally I never had a pi, I don't plan on getting one because it's too slow, and I never plan on using wifi for thin clients because it's terribly slow
20:25
So slow + slow ==> unusable...
20:25
<gbaman>
yes yes, but is it possible?
20:25
<alkisg>
Sure
20:26
<gbaman>
ok...
20:28
is it easy?
20:36
<effenberg>
Pi as client or server?
20:36
<ogra_>
lol
20:36
that was a rhetorical question i hope :)
20:36

pi as a fat client

<Lumiere>
pi doesn't really have enough power for a fat client
20:54
it really isn't a good option
21:00
<gbaman>
it does, works perfectly fine
21:02
We basically want the functionality of LTSP, but also access to the local hardware on the pi
21:03
like GPIO pins
21:03
stuff like booting from a network image, so only 1 mast image
21:03
*master
21:20
We have it already booting fine and it runs at a similar speed to a normal pi, we are not loosing much speed if any
