It starts as a NULL pointer, then might get set as a pointer to optarg,
then it might get set to point to an argv parameter, then it might have
a string value copied into it, over-writing the original data. We should
not risk over-writing internal variables which might get used for something
else (it's rude and security risk). Set up "when" as its own buffer
that has data from optargs and/or argv copied into it.
Minor code fixes across multiple source files to avoid buffer
overflows, or uninitialized strings.
the command now passes the "-h -P" flags to shutdown. This
in turn sets the INIT_HALT environment variable to POWEROFF.
Assuming this value is checked by initscripts during the
shutting down procedure, it should cause the system to
be powered off.
If halt is called without -p then the value of INIT_HALT
is not set and the default action (often set in /etc/defaut/halt)
is taken.
produced by bootlogd. The output is displayed cleaned up so there
are no control characters. This avoids the need to use sed or related
tools to try to clean up the contents of the log.
Closes Debian bugs #815839, #905245 and #890478
Added -f <format> option to pidof program to allow printf
style formating.
Closes Debian bug #571590
Thanks to Philipp Marek for the patch.
as LILO is rarely used outside of the Slackware family these days.
Switched stty flags to use ECHOE instead of ECHOPRT. This should
give smoother, more natural backspac-erase behaviour on emergency
consoles. (Created in init -b mode.)
message appear less often. The -q flag causes messages to only appear at the
10 minute, 5 minute and x-hour intervals.
The -Q flag maintains complete silence up until the final "now" warning.
init will try to open its own console. If not, then any console=
parameters will be ignored. This avoids conflicts with native kernel
created consoles.
displaying output. In this mode pidof simply returns true or false
without displaying PID values.
Updated manual page with new -q (quiet) mode.
Added -h flag for pidof, which was recognized before, but not used.
The -h flag now displays brief usage information for pidof.
This information can be read by the "runlevel" command as well as "halt"
and "reboot". Having the information logged in /var/run/runlevel as
well as the utmp file means systems without utmp (like those running
the musl C library) can still check the current runlevel. This is
useful when running halt/reboot as these programs want to check the
runlevel.
Updated the changelog, and manual pages for halt and runlevel.
from /var/run/runlevel. Added test code to runlevel.c to confirm it works.
Will use this to save/restore runlevel on systems where utmp is not
available.
