overlayfs update for 4.2 ==> supposedly supports NFS as lower dir
09:34
So if it's working, we're ok for the next debian + ubuntu...

Meh. For once, I prefer the Ubuntu overlayfs patched implementation to the kernel's upstream implementation... it behaves much worse
10:24
<ogra_>
we should just have kept aufs for another year until the dust has settled ;)
10:24
(yeah, i know, wouldnt help debian indeed :) )
10:25
<alkisg>
The problem is in Ubuntu now, the kernel's overlayfs sucks so much it's impossible to have a cow view of a filesystem that contains submounts...
10:25
(e.g. for ltsp-cleanup)
10:25
While in 14.04, with the Ubuntu's patched implementation, it works fine...
10:25
(I'm testing in 15.10 now...)
10:25
<ogra_>
ah

Hi, the LTSP on Ubuntu 15.04 and presumably also on Ubuntu 14.10 is not generating pxelinux.cfg/default
11:33
On Ubuntu 14.04 it works

Besides manually generating the files is there an elegant fix?

Is there a way to put all image files onto the hd of a fat client and boot it (by grub) in ltsp-mode but without any network connection?

alkisg: what's the overlayfs problem you mentioned earlier?
19:54
<alkisg>
!local-boot
19:54
<ltsp>
local-boot: If you want LTSP fat clients on a low-speed network, you can put i386.img on e.g. C:\Boot\LTSP\i386.img and use this command line in pxelinux.cfg: APPEND ro initrd=ltsp/i386/initrd.img init=/sbin/init-ltsp root=/dev/sda1 rootflags=ro loop=/Boot/LTSP/i386.img; IPAPPEND 3

<alkisg>
vmlintu: https://bugs.launchpad.net/ltsp/+bug/1352038
19:55
ltsp-pnp tries to create a cow view of the server's /
19:56
But if the server has e.g. /boot in a different partition, overlayfs can't merge those contents like previously... or like aufs can
19:59
<vmlintu>
interesting.. I thought that the upstream overlayfs had the same features as the old patches..
20:01
<alkisg>
It's also misbehaving a lot, with overlays showing as a child of themselves on certain conditions... while the previous patched ubuntu implementation doesn't have those issues
20:02
<vmlintu>
hmm.. we are running 4.0.x kernels on some devices, but so far I haven't noticed any problems.. Maybe I need to dig this a bit..
20:02
<alkisg>
Are you using ltsp-pnp with a separate /boot ?
20:03
(partition)
20:03
<vmlintu>
no, we are not using ltsp-pnp, but chroots
20:04
Have there been problems on client devices with the new overlayfs?
20:06
<alkisg>
I'm still on 12.04, so I'm not sure :)
20:07
<vmlintu>
some new laptops don't work properly if you have anything older than 4.0
20:08
<alkisg>
We're using the lts-trusty kernel, I haven't seen anything not working with that yet...
20:08
Are you sure 3.13 isn't enough, and 4.0 is needed?
20:09
<vmlintu>
Had to update the intel xorg driver also to get those stable. 4.0 fixed a lot of suspend problems
20:09
<maldridge>
4.x fixes a ton of stuff on intel
20:10
<alkisg>
Thanks, I'll keep that in mind
20:10
<vmlintu>
all netbooting clients are running on 3.13 or 3.16 or something similar fine
20:12
The xorg intel driver in trusty is broken on Broadwell - if you drag something too big on the screen, it crashes

15.04 has a working version
