1. Enable Linux compatibility

This can be enabled by loading the Linux kernel module kldload linux and kldload linux64 for 64-bit compatibility. To check if it is really loaded see the output for kldstat.

1.1. Enable at boot time.

Add below to vi /etc/rc.conf

linux_enable="YES"

1.2. Mount linprocfs

Some linux programs need linprocfs to be mounted on /compat/linux/proc. This can be done by adding below to vi /etc/fstab

linprocfs   /compat/linux/proc    linprocfs   rw    0   0

1.3. Mount linsysfs

Some linux programs need linsysfs to be mounted on /compat/linux/sys. This can be done by adding below to vi /etc/fstab

linsysfs   /compat/linux/sys    linsysfs   rw    0   0

1.4. Mount tmpfs

Some linux programs need tmpfs to be mounted on /compat/linux/dev/shm. This can be done by adding below to vi /etc/fstab

tmpfs   /compat/linux/dev/shm    tmpfs   rw,mode=1777    0   0
