elad 34edb026e5 Keep an internal variable indicating whether securelevel is present, and 
don't blindly try to get/set it. Prevents error messages that don't make
sense if securelevel isn't supported by the kernel.

apb a194a42669 If MAKEDEV exits non-zero, but was nevertheless able to create 
/dev/console, then have init(8) just print a warning instead of
exiting.

apb edf9f9968b No need to pass "-ppax" to MAKEDEV now that MAKEDEV internally defaults 
to using pax.

dyoung 7663f13790 KNF. 2007-03-21 03:51:30 +00:00
apb 7c0e506d3c Adapt to the new MAKEDEV interpretation of -M by passing -MM. 
Also pass "-ppax" in an attempt to get improved performance,
but this doesn't really work in the typical case, because the
install ramdisk image contains a version of pax(1) that doesn't
support the -M flag.  (MAKEDEV detects the failure and falls back
to using mknod(8) as usual.)

dsl 1d350026de Instead of creating the mfs /dev here, get MAKEDEV to do it. 
Removes a load of code that is easier done as a script.
Whenever init exits, use a different error number. Since it is difficult
for init to output messages when /dev/console is absent, having the exit
code reported by the kernel panic gives a chance of identifying the fault.
Also exit if MAKEDEV fails to create /dev/console.

apb c3bbc70fa0 When calculating the size of the MFS /dev file system, round file sizes 
up to a multiple of 512.  (Not doing this before was wrong but probably
asymptomatic, because there was enough slack space to cope with the
error).
 2007-03-01 18:25:58 +00:00
apb c654f7abce When creating /dev in a memory file system, include all three of 
MAKEDEV, MAKEDEV.subr and MAKEDEV.local in the set of files that are
copied if they exist.

Now booting an INSTALL kernel with an embedded ramdisk correctly creates
/dev again, fixing a problem introduced when MAKEDEV.subr was created a
few days ago.

tron e3f6d993ed Increase the numbers of inodes available on the "/dev" MFS to 1280. 
This should fix the "sysinst" problems caused by adding more devices
node to resolve PR port-amd64/35532.

ok by elad.

christos 6accae529c Error message consistency: 
1. don't print the program name in the message [syslog does it]
2. no extraneous \n [syslog takes care of it]
3. quote strings as `%s' [we are using syslog]
4. use %m instead of error = %d

he fa8dee8628 Um, correct previous, so that current_state def/use is consistent. 2006-09-23 18:57:26 +00:00
he 54f712bd18 Since current_state is conditionally defined, make sure its uses are as well. 2006-09-23 14:04:26 +00:00
christos c34b6372d0 Try entertain who(1) because it has been sad since it was swallowed by the 
Death Star: add utmpx entries for boot time, down time, run level, login
process.

salo b0b7590bc7 Add support for running multi-user in a chroot() environment. 
How it works:

- after successful execution of /etc/rc, check the value of "init.root"
  sysctl node, if it's different than "/", chroot() into its value and run
  /etc/rc inside the chroot(),

- in single-user, return back to the original / file system.

Allows running with / file system on e.g., cgd(4), vnd(4) or ccd(4) volumes.

Idea first discussed with Matt Thomas, implemented by Jachym Holecek <freza
(at) liberouter.org> with some nitpicks by me.  Successfully used by me for
almost a year with / on a cgd(4) volume (for more information about the setup
check ftp://ftp.NetBSD.org/pub/NetBSD/misc/salo/init-chroot/ ).

This fixes Coverity CID 2023.

While here also return NULL if the malloc fails.

christos 2c6eadc9ce Move WARNS=3 to the Makefile.inc, and add a little const to the remaining 
programs that did not compile before.

dsl 920dff4b7c If /dev/constty exists, use it instead of /dev/console for single user shell. 
I'm not 100% certain it should call login_tty() for anything else.
 2003-10-03 13:31:32 +00:00
dsl 58915e2274 If /dev/MAKEDEV is a symlink then preserve the symlink in the mfs /dev. 
If /dev/MAKEDEV doesn't exist then try to run /etc/MAKEDEV instead.
Use the (new) '-n inodes' option to mount_mfs and base the size on the number
of inodes and the size of the MAKEDEV script.

lukem b96069c077 Always compile in support for attempting to obtain the major device 
number of the console from sysctl("machdep.console_device"), rather
than making in optional on the (unused) #ifdef DEBUG.
Certain platforms do not have the console at makedev(0,0) (including
many arm32 and some sh3 platforms), so the "mfs MAKEDEV" hack would
have failed on those.

Noted in private discussion with Quentin Barnes.

lukem 35c2bddeea If RESCUEDIR is defined, use that as an alternate path to sh and mount_mfs, 
and prepend RESCUEDIR to the default PATH.
(This replaces my _PATH_ALTSHELL mods from rev 1.52 of init.c)
