Package: munin
Version: 2.0.57-1
Severity: normal
By default, debian's munin is not ready for switching html_strategy and
graph_strategy to cgi because of a lack of access permission for the (apache2)
www-data user on folders /var/lib/munin/cgi-tmp and /var/log/munin .
This can be resolved by allowing the respective owner groups write access
> chmod g+w /var/lib/munin/cgi-tmp /var/log/munin
.. and adding the www-data user to the owning groups for both:
> gpasswd -a www-data munin
> gpasswd -a www-data adm
With this, the cgi strategies work beautifully, including dynazoom.
