Hello,
syntax of /etc/tangorc should be cautious of its effects.
Daemons like tango-db use this file.
In /etc/init.d/tango-db, some environment variables are not quoted:
$ sed -n '55p' /etc/init.d/tango-db
if [ $CANON_HOST = "localhost" ]
In some specific cases, it can generate some error like
Feb 27 11:05:48 HOSTNAME tango-db[6455]: /etc/init.d/tango-db: line 55: [: =: unary operator expected
It is the case for example if TANGO_HOST definition in /etc/tangorc begins with something else than spaces (if it begins with export command).
Warning:
documentation explains how to define TANGO_HOST.
If you want to export command, beware to not add the export at the begining of the line but after TANGO_HOST definition line.
If not, tango-db can fail at startup because not founding.
The good practice is probably to source /etc/tangorc when needed and then to export TANGO_HOST (or sourcing it in ~/.bashrc followed by export TANGO_HOST)
