from `sys/geom/geom_subr.c': /* If foot-shooting is enabled, any open on rank#1 is OK */ if ((g_debugflags & 16) && pp->geom->rank == 1) ; this was introduced by phk@ himself in: commit 641a10a0cb4ca86785ef13fce9343bc34c30f326 Author: phk <p...@freebsd.org> Date: Wed Feb 12 09:48:27 2003 +0000 Implement a handle for efficient implementation of perforations in lower extremities. Setting bit 4 in debugflags (sysctl kern.geom.debugflags=16) will allow any open to succeed on rank#1 providers. This will generally correspond to the physical disk devices: ad0, da0, md0 etc. This fundamentally violates the mechanics of GEOMs autoconfiguration, and is only provided as a debugging facility, so obviously error reports on GEOM where this bit is or has been set will not be accepted. - Arnaud _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
