What I was saying is that disabling taste LF> system wide (i.e., in the geom subsystem) cannot work. LF> Am I wrong? system-wide is bad idea, but it is the case when user want to disable SOME tasting. For example, all these snapshots should not be tasted by anything, but, MAYBE, DEV GEOM. And, maybe, even not by DEV GEOM -- typically they should not be seen in /dev in "normal" life. --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
