It's basically a very stripped-down installation of RedHat Linux which is necessary to run actual RedHat Linux (and other Linux distributions) applications. The actual emulation of the Linux kernel is done inside the FreeBSD kernel (if you choose to enable this option) and does not require installation of any packages, but in order to run most Linux binaries you need the userland support code (libraries, configuration files, system commands, etc) which they expect to find on the system. > There are several complete operating systems that are less than 60 > megabytes in size (i.e. MS-DOS, Minix). Yes, but Linux is not one of them.
