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/ ).

chris 4727225848 Fix case where argv wasn't returned or freed. 
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.

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.

lukem 9f3703ab9a - use _PATH_ALTSHELL (which defaults to _PATH_BSHELL) as the default ALTSHELL 
(as opposed to _PATH_BSHELL), to allow the ALTSHELL to be changed.
- print the full path to the default shell in the ALTSHELL prompt.

mycroft e84a828ff1 In single-user, after taking a signal and having the `shell' die with 
SIGKILL, go into an infinite loop (like in the runcom SIGTERM case), on the
assumption that reboot(8) is in the middle of taking the system down.
This fixes `panic: init died' from sysinst.

christos 62a708c06d KNF: - use %m always instead of sometimes using strerror() 
- space problems in casts
     - don't cast 0, use NULL
     - don't have long lines
     - don't cast malloc
     - use warn/warnx instead of fprintf
     - fix bug where a failed mount_mfs would cause the program to continue.
     - pass lint

abs c48a08886b Rename MSDOSFS_ROOT to MFS_DEV_IF_NO_CONSOLE, and rework: 
- Always attempt mfs dev if missing /dev/console
    - Save and run both MAKEDEV and MAKEDEV.local
    - After creating the mfs dev, mknod() and freopen() /dev/console.
    - If MAKEDEV is missing do not fail out early, but still create the mfs,
      /dev/console.
    - If we hit any errors fail out to single user.
This change _only_ affects systems booting without /dev/console.

tls 566ff31cb7 When downgrading from 'highly secure' mode (securelevel >= 2) to 'insecure' mode (securelevel 0) and the root password is set, always require it before giving a shell on the console. Reasoning: if an attacker has access to the machine console, he doesn't necessarily have access to the hardware itself; on a 'highly secure' machine, we may as well make his life hard. 1998-11-14 07:17:58 +00:00
