DESCRIPTION
A sketch of the filesystem hierarchy.
/ Root directory.
/altroot/
Alternate (backup) location for the root (`/') filesystem.

ronments. These programs are statically compiled and therefore
do not depend on any system libraries to run.

at boot-time).
/dev/ Block and character device files.
MAKEDEV Script for creating device files (see makedev(8)).
fd/ File descriptor files (see fd(4)).
/emul/ Base directory for alternate areas searched first when system
call emulation is in effect (see compat_bsdos(8),
compat_freebsd(8), compat_ibcs2(8), compat_linux(8),
compat_sunos(8), compat_svr4(8), compat_ultrix(8)).

/sbin/ System programs and administration utilities fundamental to both
single and multi-user environments.
/stand/ Programs used in a stand-alone environment.
