If I understand correctly, you want to use the jail to run a 4.11 userland on an 8.x kernel? If you are not running GENERIC on the host, remember to include the COMPAT_FREEBSD4..COMPAT_FREEBSD7 options in your kernel. You'll need that to run 4.x binaries. Running older binaries is possible. But on the other hand running a userland that is not in sync with the kernel not supported and known to be able to cause trouble. See e.g. ยง24.7 of the Handbook. It will be an interesting experiment at least. :-) I'd probably try installing 4.11 on a old spare machine first. > Yeah, you could consider it 'embedded' all right.

Old+'dusty corner'+'critical' is not a good combination in my experience. If the scenario also contains the element 'no backups', its time to run for the hills. :-/ Roland -- R.F.Smith http://www.xs4all.nl/~rsmith/ [plain text _non-HTML_ PGP/GnuPG encrypted/signed email much appreciated] pgp: 1A2B 477F 9970 BA3C 2914 B7CE 1277 EFB0 C321 A725 (KeyID: C321A725)
