[Ltsp-discuss] Debian upgrading thin client kernel

[Michael Pope]

I'm running LTSP on a Debian Wheezy server and in my Chroot area I'm
using Debian 'testing' due to hardware compatibility for some thin
clients in the kernel. Currently the kernel on the thin clients is 3.16
and I would like to upgrade this to 4.3 which is in the Debian Testing
respository. The reason I need the new kernel is one of the thin clients
requires the latest kernel for video driver support, without it the
windows moves around the windows manager really slow.

The problem is after I upgrade the kernel and boot a thin client I get
the following error;
Operation failed: No such file or directory (repeated many times)
[FAILED] Failed to start Create Volatile Files and Directories
See 'systemctl status systemd-tmpfiles-setup.service' for details


Here are the commands I used to upgrade the kernel
$ ltsp-chroot -m
Need to install headers & image for the 4.3 pae kernel (download only)
# apt-get install -d linux-headers-4.3.0-1-686-pae
linux-image-4.3.0-1-686-pae

Install
# apt-get install linux-headers-4.3.0-1-686-pae linux-image-4.3.0-1-686-pae
# exit

Update the kernel
# sudo ltsp-update-kernels

Update the image
# sudo ltsp-update-image

When I boot the thin client after the kernel upgrade the login manager
screen is displayed and when I hit 'ctrl-alt-F1' I'm presented with the
error which I've attached.

I've now reverted to a snap shot I took before doing all this so that
work can continue. It's a little tricky to test anything straight away
as people have to use these systems for work.

You can also get the 4.3 kernel from jessie-backports, which should be a
little less disruptive than using Debian Stretch/Testing for the whole
chroot. You'll also need to get ltsp from jessie-backports as well, as
the newer kernels aren't backwards compatible with older versions of
LTSP due to incompatibilities in the upstream "overlay" fs support.

On a related note, Probably a good idea to get your server upgraded to
Debian Jessie/Stable, before Wheezy/Oldstable goes out of support.

Are you experiencing any problems, or just alarmed about the error
message?

What's the output of:

Install
# apt-get install linux-headers-4.3.0-1-686-pae linux-image-4.3.0-1-686-pae

Do you need to compile custom modules for the kernel, or other custom
software that relies on the header files?
