using a symbolic link. (ie /tmp/sleep when /tmp/sleep links to /usr/bin/sleep).
This is now fixed as we check both the realpath and symbolic path for processes.
In other words, "pidof /tmp/sleep" and "pidof /usr/bin/sleep" will return
the same PIDs when /tmp/sleep is a symbolic link to /usr/bin/sleep.

* Add check for console using TIOCGDEV on Linux systems in bootlogd to
make finding console more robust. - Provided by Alexander Vickberg
Added ability to use "@" symbol in command named in the inittab file. This
treats commands as literal and does not launch a shell to interpret them.
Updated inittab manual page to include overview of symbols which trigger
a shell interpretor and how to disable them using the @ symbol.
hanging if NFS mounts are not responding.
Default to showing processes in the uninterruptable state (D).
The -z flag no longer affects whether processes in D state are shown.
The -z flag does still toggle whether zombie (Z) processes are shown.
a wider range of consoles. The console name is already passed in from the
kernel command line using "console=". We no longer filter out names as strictly
but do now check to confirm the "console=" device points to a valid TTY.
in the format +hh:mm. This is in addition to the existing formats such as
hh:mm, +m, and "now".
Cleared up compiler warning in dowall which can happen if the
output message is longer than the size limit on the snprintf()
buffer. This is not a bug, a the trucation works, but using a larger
buffer avoids the warning on systems with long user/host names.
Cleaned up some output from readbootlog.
Added -e flg to bootlogd. When -e is used, data saved
to the boot log file does not have escape characters
removed. This means colour and cursor movement codes
stay in the log file. The may then look nicer when
read with "less -R', but may appear cluttered or
out of alignment when viewed with other, plain-text tools.
can happen without a near-full-second delay after
all processes have terminated. Replaced do_sleep()
with do_msleep(), provided by Serge Belyshev.
Replaced hardwired sleep constants in init.c with
defined constants for easy updating in the future.
could be used to print information from memory or crash
pidof. Replaced flag with "-d" which allows for a custom
separator to be used between listed PIDs.
Patch supplied by KatolaZ.
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.
