Currently, if mkdesktop detects that Linux emulation is to be enabled, it will also add the following mounts to fstab: tmpfs /compat/linux/dev/shm tmpfs rw,mode=1777,size=1g 0 0 linprocfs /compat/linux/proc linprocfs rw 0 0 linsysfs /compat/linux/sys linsysfs rw 0 0 https://github.com/bourne-again/mkdesktop/blob/master/mkdesktop#L228C1-L230C46 It also runs kldload for linux & linux64. https://github.com/bourne-again/mkdesktop/blob/master/mkdesktop#L195 These are now managed by the linux service. It should be sufficient to sysrc linux_enable=YES service linux start
