If I'm reading this correctly, in the future it'll be extremely easy to boot an LTSP chroot via a VM, for easy maintenance: https://www.phoronix.com/scan.php?page=news_item&px=VirtIO-FS-Folder-Sharing-VM

hm. it says it uses fuse, but it's not clear if that's a layer on top of normal files, or its own fuse fs, though i guess the chroot could live on fuse too

it seems to be, but performance lack. might be fine for the occasional edit where chroot won't do

Is anyone here running LTSP on AWS or has any tales regarding such?
20:49
I would presume there are no issues with hosting an LTSP server on AWS, provided it is of a suffiecient spec to meet the load
20:50
<||cw>
danboid: I guess it's technically possible, you'll need a stupid fast internet connection to make it usable. the network is usually the weak link
20:50
even 100Mbit is on the slow site for all but the most basic usage
20:51
site/side/
20:52
<danboid>
Of course. I've not tried LTSP on 100Mb yet. We'll be using fat clients
20:53
<highvoltage>
so... you'll just be using AWS as storage essentially
20:56
<danboid>
None of you have ever tried integrating LTSP with AWS or similar? Have you heard of anyone doing so with success?
20:58
<alkisg>
danboid: the ltsp server for fat clientsmostly needs bandwidth, not cpu. Better to use a pentium 4 with a gigabit nic, than a remote monster server
21:01
So personally I wouldn't even waste time testing that "remote fat client server" scenario
21:01
<highvoltage>
danboid: it's an odd fit and you'd still need a local dhcp server
21:01
danboid: so the question then becomes "what's the point"
21:01
<alkisg>
!local-boot
21:01
<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
21:01
<highvoltage>
AWS is horrible typically on di/o bandwidth anyway
21:01
<alkisg>
This ^ could make things a bit better for remote servers... but still yeah, what's the point
21:03
<danboid>
It's something I've been asked to consider / look into as a possibility. I'm struggling to see any benefit in using AWS or similar at all myself
21:03
<alkisg>
Are you currently using ltsp? (the persons that asked you to look into this)
21:04
<danboid>
Yes, 16.04 fat clients and its generally running great, except power off doesn't work
21:04
they reboot instead
21:04
<alkisg>
Yeah that broke later on by systemd updates, but I've only fixed it in 18.04
21:05
<danboid>
Ah right! Good to hear its fixed in 18.04
21:05
<alkisg>
And why are they looking to change to a remote server, any ideas there?
21:06
<danboid>
Its part of a 'cloud first' strategy
21:06
<highvoltage>
lol well it's their funeral.
21:06
<danboid>
In some areas it doesn't make sense and I think LTSP is one
21:07
<alkisg>
I don't think cloud works well yet for remote booting, remote gaming, remote desktop (well slow remote desktop works)
21:08
<danboid>
Totally agree
21:11
Thanks for your thoughts. It's pretty much exactly what I thought you'd say
21:14
Have there been any big-ish deployments of 18.04 LTSP yet?
21:14
Is it deemed stable yet?
21:18
<alkisg>
danboid: http://www.ltsp.org/stories/widget-map/?location=Greece
21:19
Personally I think it's much more stable than 18.04, since I support it in hundreds of schools, while we stopped supporting 16.04 there
21:19
<danboid>
Much more stable than 16.04
21:20
Sounds promising
21:20
<alkisg>
(regarding ltsp, that is; for individual apps like gcompris or whatever, your milage may vary)
21:24
<danboid>
I wrote a script that detects the GPU of the LTSP clients and disables the non-free NVIDIA driver so we can get accelerated gfx on all machines with one LTSP image. Will my script not be required in 18.04?
21:25
<alkisg>
This is a question for #ubuntu-x; but afaik, nvidia drivers can now peacefully coexist with xorg drivers, so I imagine that yes, your script won't be needed
21:26
It's close to midnight here though, /me waves, until tomorrow... :)
21:26
<danboid>
Good night! Thanks!
