Author: sobomax Date: Wed Mar 9 19:36:25 2016 New Revision: 296574 URL: https://svnweb.freebsd.org/changeset/base/296574 Log: For the MD_ROOT option don't inject /dev/md0 as root dev when ROOTDEVNAME is defined explicitly. It's kinda pointless and results in extra step in boot sequence which is not really needed, i.e.: md0: Embedded image 1331200 bytes at 0x8038b7b4 Trying to mount root from ufs:/dev/md0 []... Mounting from ufs:/dev/md0 failed with error 22. Trying to mount root from ufs:md0.uzip []... warning: no time-of-day clock registered, system time will not be set accurately start_init: trying /sbin/init Modified: head/sys/dev/md/md.c head/sys/modules/md/Makefile Modified: head/sys/dev/md/md.c ============================================================================== --- head/sys/dev/md/md.c Wed Mar 9 19:06:46 2016 (r296573) +++ head/sys/dev/md/md.c Wed Mar 9 19:36:25 2016 (r296574) @@ -58,6 +58,7 @@ * From: src/sys/dev/vn/vn.c,v 1.122 2000/12/16 16:06:03 */ +#include "opt_rootdevname.h" #include "opt_geom.h" #include "opt_md.h" @@ -1732,7 +1733,7 @@ md_preloaded(u_char *image, size_t lengt sc->pl_ptr = image; sc->pl_len = length; sc->start = mdstart_preload; -#ifdef MD_ROOT +#if defined(MD_ROOT) && !defined(ROOTDEVNAME) if (sc->unit == 0) rootdevnames[0] = MD_ROOT_FSTYPE ":/dev/md0"; #endif Modified: head/sys/modules/md/Makefile ============================================================================== --- head/sys/modules/md/Makefile Wed Mar 9 19:06:46 2016 (r296573) +++ head/sys/modules/md/Makefile Wed Mar 9 19:36:25 2016 (r296574) @@ -3,6 +3,6 @@ .PATH: ${.CURDIR}/../../dev/md KMOD= geom_md -SRCS= md.c opt_md.h opt_geom.h vnode_if.h +SRCS= md.c opt_md.h opt_geom.h opt_rootdevname.h vnode_if.h .include <bsd.kmod.mk>
