Exciting ... In some way, muLinux itself is born with "meiosis", because
I merget genetic material from RedHat 4.2 and Debian 1.3. After that,
very lazy, muLinux choose to clone itself using "mitosis", because
partner is difficult to find for a floppy system.

So, "autofecondation" and "parthenogenesis": parthenogenesis? Is this
name related to Venus, borned from the sea?
