IIUC, a better example would be host=8.2, jail1=8.1 and jail2=8.0. A point release is not supposed to make any incompatible changes to the kernel ABI, but it might add new interfaces not present in the older kernel. > But host=8.2 and jail1=9.0 will have unknown reliability. I would say it is only an accident if (jail major > kernel major) works, because the KABI will likely have changed between N.x and (N+1).x. However, host=9.0, jail1=8.x should work if the host kernel includes the COMPAT_FREEBSD8 option. > Technically there is no checks stopping someone from doing this > and from the outside all will look correct, but it will fail and > you may lose both the host and jail. You may indeed lose the jail, but if _anything_ done in the jail is able to corrupt the host there is by definition a bug in the host's jail support. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
