All small derived systems... Although the picoBSD'ers use it as `their'

What ye do to the /etc and /dev entries in / ? Just curious...

Cool... If ye are cvsupping CURRENT, ye have no doubt seen the picobsd entry ;)
At least ye have the makefiles *G* (Hey Andrzej, mayhaps we oughtta get him to

We simply link to CURRENT with our own sources afaik... =)
