Subject: ltsp-client-core: the init script should provide a hook for code snippets

Date: 6 Apr 2013 15:58:09 +0200

[Message part 1 (text/plain, inline)]

Package: ltsp-client-core
Version: 5.4.2-6
Severity: wishlist

Hi,

to fetch config values out of LDAP and to add them to those provided on 
the kernel command line or in lts.conf, code has to be executed inside 
of the init script. While it is possible to modify the init script in 
such a way using a script in init-ltsp.d [1], it would be better to have a 
hook inside of the initscript serching for code in some directory, say 
ltsp-client-core.d

# Save as /usr/share/ltsp/init-ltsp.d/70-edu-client-core
# This snippet modifies /etc/init.d/ltsp-client-core on-the-fly.
#
# Get config stored in LDAP for Debian Edu ltsp clients (thin and fat).
#
sed -i '/"Starting\ LTSP\ client..."/ a\
        /usr/share/ltsp/get-ldap-ltsp-config\
        cat /var/cache/ltsp/ltsp_config_edu >> /var/cache/ltsp/ltsp_config_env\
        ' /etc/init.d/ltsp-client-core

Or you could also use /usr/share/ltsp/ltsp_config.d...

Why is this better to do it from ltsp-client-core?

Why don't you call get-ldap-ltsp-config from ltsp_config.d or init-ltsp.d
instead?


live well,

First location I tried, but it didn't work out for me.

Cause then a network connection to the LDAP server is possible.

Tried both locations; init-ltsp.d is far to early. As far as 
ltsp_config.d is concerned, it seems to be the same (no connection to 
ldap server). So this weird workaround. The script get-ldap-ltsp-config 
is attached, maybe you're able to figure our some other way.

close 704830
thanks

Finally found a way to fetch lts.conf values using a script in init-ltsp.d,
thanks again for your hints.
