Subject: ltsp-client-core: SERVER in lts.conf ignored, wrong order in ltsp_config.d

Date: Thu, 04 Oct 2012 23:09:50 +0200

Package: ltsp-client-core
Severity: normal

In my setup the server that is logged into is different from the NFS
server serving the rootfs. By default ltsp assumes those are the same,
to override one can set the SERVER variable in lts.conf.

However this doesn't work. This is because in ltsp_config.d the script
01-getltscfg comes before 01-ltspconfig-cache, which means the later
will override the SERVER variable from lts.conf with a guess based on
the NFS server IP.

The solution is simple, just rename 01-ltspconfig-cache to
00-ltspconfig-cache

What version of ltsp are you running? From the ltsp server, please paste the 
output of runnning:

  ltsp-info

(or if you're willing to, ltsp-info --verbose)

You probably should use LDM_SERVER (or XDM_SERVER) to select the login server,
not the SERVER variable.

This may have other other unintended side-effects- I'll look into it.

Well, with server you said all *_SERVER vars.

Doing a simple grep, it seems that the only thing that is happening is
that in init-ltsp.d a few variables are cached and reloaded in
01-ltspconfig-cache. 

It is documented everywhere that you can override these variables by
setting it in /etc/lts.conf, in the current setup you can't.

SERVER is also used to define other variables; when I was testing your proposed 
change, it also changed the NBD_SWAP_SERVER variable and caused that to fail.

But it's the documented behavior, and is still useful in some cases, as long as 
you're aware of the consequences, so...

Changes: 
 ltsp (5.4.2-3) unstable; urgency=low
 .
   * ltsp-client-core patches from upstream:
     - Fix use of 'echo -e' by switching to printf in screen-x-common
       (Closes: #692920).
     - Fix use of a "read -p" bashism in ltsp-cleanup (Closes: #690638).
     - Fix dashisms in update-kernels using "local -" by saving flags and
       restoring them later (Closes: #693499).
     - Prevent setting of LTSP_FATCLIENT variable from causing ltsp-client-core
       initscript to die (Closes: #693745).
     - Move ltspconfig cache processing earlier, so that variables defined in
       lts.conf can override autodetected variables (Closes: #689668).
     - Fix initramfs udhcp hook to use /run instead of /tmp, which allows the
       booting from a network using PXE ProxyDHCP (Closes: #693746).

   * ltsp-server patches from upstream:
     - Fix bashism in ltsp-config by using printf instead of 'echo -e' and echo
