I put new phpmyadmin into community-testing
To use it you should:
- add FollowSymlinks options
- append directories to php.ini
open_basedir = /usr/share/webapps/:/etc/webapps
- change web-alias to /usr/share/webapps/phpMyAdminWhat do you think about this solution? (I hope all webapps can be adjusted with symlinking)
