Directory layout

The directory layout you see depends upon the mode you are working in. If you are working in Linux mode, you will see a Linux directory tree, but if you are working in UNIX mode, you will see a UnixWare 7 directory tree. For information about modes, see ``Understanding modes''.

Most directories are unique to the environment they reside in, but /home and /tmp are shared (via lxuwfs) by both UnixWare 7 and LKP environments: Some administrative files are also linked between the two environments. See ``Directories and files''

From UNIX mode, the directory layout looks like this (/ = UnixWare 7 root):

Directory layout from UNIX mode

From UNIX mode:

• access to /filename goes to /filename (an UnixWare 7 file)

• access to /linux/filename goes to /linux/filename (a Linux file)

• access to /linux/unixware goes to / (the UnixWare 7 / directory)

Directory layout from Linux mode

From Linux mode:

• access to /filename goes to /linux/filename (a Linux file)

• access to /linux/filename goes to /linux/filename (a Linux file)

• access to /unixware/filename goes to /unixwarefilename (an UnixWare 7 file)

So, regardless of whether you are operating from UnixWare 7 or Linux mode:

• filenames beginning with /unixware always reference an UnixWare 7 file (except for /unixware/linux)

• filenames beginning with /linux always reference a /linux file (except for /linux/unixware)

• an executable beginning any other way is run in the proper environment depending on whether it is a UNIX or Linux binary. See ``Running application binaries''.

This layout makes it possible to run Linux applications and allows Linux programs to access UnixWare 7 files. A program could access /etc/inittab, /linux/etc/inittab, or /unixware/etc/inittab, and would access the correct version of the file in each case.
