Bug#178382: dpkg install multiple versions of programs
is there a possibility to install packages, and then "activate" the
software? you would need 2 directories:
1. installation directory
2. activation directory
why somebody would need this?
1. you are able to separate the task of copying
the software (install), and adding the software
to paths or linking to the right directories.
2. this is good, if you have to distribute software
to thousands of computers
3. this is good if your software is unstable, and
you want to switch back fast.
- install subversion to /export/opt/subversion/0.16/
- activate subversion to /opt/subversion
by: ln -s /export/opt/subversion/0.16 /opt/subversion
- if you upgrade,
- you install to /export/opt/subversion/0.17
- you deactivate version 0.16.
- you activate version 0.17.
- later on, you might remove version 0.16.
- install java to /export/opt/jdk/1.4.1_05
- activate java to /opt/jdk
this also creates softlinks /opt/bin/java
or adds /opt/jdk/bin to paths
thanks for your attention .....
