.Nm COMPAT_LINUX
.Nd setup procedure for running Linux binaries
.Sh DESCRIPTION
NetBSD supports running Linux binaries. This applies to i386 systems
and Linux a.out binaries only for now. Most binaries should work,
except programs that use Linux-specific features. These include
the Linux /proc filesystem (which is different from the optional
NetBSD /proc filesystem), and i386-specific calls, such as enabling
virtual 8086 mode. The Linux compatibility feature is active
NetBSD supports running Linux binaries. This only applies to i386 systems
for now. Both the a.out and ELF binary formats are supported. Most programs
should work, including the ones that use the Linux SVGAlib. Programs that
will not work include the Linux /proc filesystem (which is different from
the optional NetBSD /proc filesystem), and i386-specific calls, such as
enabling virtual 8086 mode. Currently, sound is not supported for Linux
binaries (they will probably run, but not produce any sound).
The Linux compatibility feature is active
for kernels compiled with the
.Nm COMPAT_LINUX
option enabled.

Extract the files from these gzipped tarfiles in your /emul/linux directory
(possibly omitting or afterwards removing files you don't need), and you
are done.
.Ss Programs using SVGAlib
SVGAlib binaries require some extra care. The pcvt virtual console driver
has to be in the kernel for them to work, and you will also have to create
some symbloic links in the /emul/linux/dev directory, namely:
.Pp
.nf
/emul/linux/dev/console -> /dev/tty
/emul/linux/dev/mouse -> whatever device your mouse is connected to
/emul/linux/dev/ttyS0 -> /dev/tty00
/emul/linux/dev/ttyS1 -> /dev/tty01
.fi
.Pp
Be warned: the first link mentioned here makes SVGAlib binaries
work, but may confuse others, so you may have to remove it again at
some point.
.Sh BUGS
The information about Linux distributions may become outdated.
