I have a simple question. In addition to use BleachBit, is it possible to remove old versions of packages in /opt ; /etc ; /bin; /usr/bin ........ etc. directories?
example, in /opt , my sabayon systems, installed and upgraded since the version 5.2, hav many older versions of Java, icedtea.bin etc...
These files and directories may be removed without broken the system?
