PICOBSD(8) FreeBSD System Manager's Manual
picobsd -- floppy disk based FreeBSD system
picobsd [options] [floppy-type [site-name]]
The picobsd utility is a script which produces a minimal implementation
of FreeBSD (historically called PicoBSD) which typically fits on one
floppy disk, or can be downloaded as a single image file from some
such as CDROM, flash memory, or through etherboot.
The picobsd utility was originally created to build simple standalone
systems such as firewalls or bridges, but because of the ability to
cross-build images with different source trees than the one in the
server, it can be extremely useful to developers to test their code
out having to reinstall the system.
