Back then, a sysctl called kern.cam.ada.legacy_aliases, which is enabled by default, was provided for backwards compatibility. Some research shows that this feature was removed in r289137 [2] It's also covered in UPDATING: 20151011: Compatibility shims for legacy ATA device names have been removed. It includes ATA_STATIC_ID kernel option, kern.cam.ada.legacy_aliases and kern.geom.raid.legacy_aliases loader tunables, kern.devalias.* environment variables, /dev/ad* and /dev/ar* symbolic links. - Michael [1] https://www.freebsd.org/releases/9.0R/relnotes-detailed.html (see 3.2.3) [2] https://svnweb.freebsd.org/base?view=3Drevision&revision=3D289137 --=20 Michael Gmelin
