I understood the MLINK part incorrectly, it should be the other way around

also remove the init mlink to securelevel. Discussed with and sharing pointyhat with: brueffer

Patches to allow one to allow one to specify a directory to chroot to.

2007-02-04T06:33:13Z

This includes support for running a script to setup that directory. The kenv variables init_chroot and init_script control this behavior, and are documented in loader(8) that's about to be committed (along with the other variables like init_path...).

use standard mode instead of 500 for /sbin/init.

2006-02-28T08:02:28Z

As discussed on -current, there is no sensitive info in /sbin/init to prevent reading it from non-privileged users, nor any reason to remove the 'x' bit as the first thing the program does is check the uid and exit if it is not run by root. Instead (and this is why i make the change), mode 500 prevents operation when exporting the partition without -maproot=0 to diskless clients. All previuos releases are affected by the same problem, so a merge to RELENG_6 at least would be appropriate (after proper re@ approval of course).

-mdoc sweep.

Fix system shutdown timeout handling by again supporting longer running

2005-09-15T13:16:07Z

shutdown procedures (which have a duration of more than 120 seconds). We have two user-space affecting shutdown timeouts: a "soft" one in /etc/rc.shutdown and a "hard" one in init(8). The first one can be configured via /etc/rc.conf variable "rcshutdown_timeout" and defaults to 30 seconds. The second one was originally (in 1998) intended to be configured via sysctl(8) variable "kern.shutdown_timeout" and defaults to 120 seconds. Unfortunately, the "kern.shutdown_timeout" was declared "unused" in 1999 (as it obviously is actually not used within the kernel itself) and hence was intentionally but misleadingly removed in revision 1.107 from init_main.c. Kernel sysctl(8) variables are certainly a wrong way to control user-space processes in general, but in this particular case the sysctl(8) variable should have remained as it supports init(8), which isn't passed command line flags (which in turn could have been set via /etc/rc.conf), etc. As there is already a similar "kern.init_path" sysctl(8) variable which directly affects init(8), resurrect the init(8) shutdown timeout under sysctl(8) variable "kern.init_shutdown_timeout". But this time document it as being intentionally unused within the kernel and used by init(8). Also document it in the manpages init(8) and rc.conf(5). Reviewed by: phk MFC after: 2 weeks

Moved descriptions of securelevels from init(7) to security(7).
