23.1.2. Installing Linux Emulation in 2.2.2-RELEASE and later

It is no longer necessary to specify ``options LINUX'' or ``options COMPAT_LINUX''. Linux emulation is done with an LKM (``Loadable Kernel Module'') so it can be installed on the fly without having to reboot. You will need the following things in your startup files, however:

1. In /etc/rc.conf, you need the following line:

   linux_enable=YES
   

2. This, in turn, triggers the following action in /etc/rc.i386:

   # Start the Linux binary emulation if requested.
   if [ "X${linux_enable}" = X"YES" ]; then
           echo -n ' linux';               linux > /dev/null 2>&1
   fi
   

If you want to verify it is running, modstat will do that:

% modstat
Type     Id Off Loadaddr Size Info     Rev Module Name
EXEC      0   4 f09e6000 001c f09ec010   1 linux_mod
