So I guess Linux service is restarted by "service linux restart"?
kldstat on my Freebsd showed only linux.ko, linus_common.ko and linux64.ko .
I had not yet actually attempted to run my small Linuxes in FreeBSD or NetBSD, not ready yet.
I still would need such things as init scripts, proc fs, /etc/fstab and other configuration files.
FreeBSD Handbook online is not sufficiently detailed.
