Linux Process File System

option LINPROCFS

The last of those kernel configuration options enables support for the Linux Process File System procfs which some Linux applications may require. The procfs normally allows applications to query process or device information from the kernel. You can add the following to /etc/fstab to ensure that the Linux procfs is mounted:

none /compat/linux/proc linprocfs rw 0 0

Note that it is mounted at /compat/linux/proc, not /proc as is usual on Linux. This is to distinguish it from the FreeBSD procfs which, if it is mounted at all, will be mounted at /proc.

Once you have updated /etc/fstab, type mount -a to mount the Linux procfs. It will happen automatically next time you boot.
