From d6da8e8c48feb8faf9287fc86fbbf0890c37a87c Mon Sep 17 00:00:00 2001 From: Roy Marples Date: Fri, 10 Oct 2008 08:37:21 +0000 Subject: [PATCH] sysinit is now a real runlevel that handles things like udev, dmesg and mounting various bits in /dev and /sys. init.sh JUST mounts /lib/rc/init.d (and /proc for Linux systems) To make development of this easier we now return an empty RC_STRINGLIST instead of a NULL for empty things. If you don't have a udev init script installed, don't reboot your box OR roll back to an older OpenRC version. --- conf.d/Makefile.Linux | 2 +- conf.d/dmesg | 3 + etc/rc.conf.Linux | 17 - etc/rc.conf.in | 16 +- init.d/Makefile.Linux | 4 +- init.d/devfs.in | 36 +++ init.d/dmesg.in | 17 + init.d/fsck.in | 2 +- init.d/procfs.in | 23 +- init.d/sysfs.in | 63 ++++ runlevels/Makefile | 9 + runlevels/Makefile.Linux | 4 +- sh/init-common-post.sh.in | 4 - sh/init.sh.Linux.in | 106 +----- src/includes/rc-misc.h | 1 - src/librc/librc-depend.c | 108 +++---- src/librc/librc-misc.c | 12 +- src/librc/librc.c | 244 +++++++------- src/rc/rc-depend.c | 27 +- src/rc/rc-misc.c | 115 +++---- src/rc/rc-service.c | 14 +- src/rc/rc.c | 215 +++---------- src/rc/runscript.c | 661 +++++++++++++++++++++----------------- 23 files changed, 777 insertions(+), 926 deletions(-) create mode 100644 conf.d/dmesg create mode 100644 init.d/devfs.in create mode 100644 init.d/dmesg.in create mode 100644 init.d/sysfs.in diff --git a/conf.d/Makefile.Linux b/conf.d/Makefile.Linux index 628636b0..74679400 100644 --- a/conf.d/Makefile.Linux +++ b/conf.d/Makefile.Linux @@ -1 +1 @@ -CONF+= consolefont hwclock keymaps modules +CONF+= consolefont dmesg hwclock keymaps modules diff --git a/conf.d/dmesg b/conf.d/dmesg new file mode 100644 index 00000000..eb065f2f --- /dev/null +++ b/conf.d/dmesg @@ -0,0 +1,3 @@ +# Sets the level at which logging of messages is done to the +# console.
