Correct out of date build configuration, porting to Solaris 11 network
link infrastructure and new libpcap logic. This additionally allows for
device drivers in subdirectories of /dev. Correct packaged nmap
personalities and signatures to work out of the box. Finally, hack
arpd logic to properly close sockets and quit on TERM by repeating
signaling in the run command script. Sadly, all this fails to correct
the run time behaviour of honeyd which fails to bind to the IP layer.

 .SH "DESCRIPTION"
 .IX Header "DESCRIPTION"
 The \fB\f(CB@l_prefix\fB@/bin/openpkg rc\fR program is the run-command (rc) processor
 of the \fBOpenPKG\fR instance \f(CW\*(C`@l_prefix@\*(C'\fR. It allows querying the rc
 configuration variables and the execution of rc command scripts of one
 or more installed \fBOpenPKG\fR packages. The implemented run-command
 facility is partly modeled after the classical \s-1UNIX\s0(tm) System V
 run-command facility plus ideas taken from the FreeBSD and NetBSD
 run-command facilities. It mainly merges the classical startup/shutdown
 procedures with periodical procedures into a single approach.

 .IX Item "@l_prefix@/bin/openpkg rc [-s|--silent] [-v|--verbose] [-d|--debug] [-k|--keep] [-D|--define name=value] package command [command ...]"
 \&\fBRun-Command Execution.\fR This executes one or more specified
 \&\fIcommand\fRs in a particular \fIpackage\fR or in all installed packages if
 \&\fIpackage\fR is "\f(CW\*(C`all\*(C'\fR". Option \fB\-\-silent\fR can be used to explicitly
 disable progress messages on \f(CW\*(C`stderr\*(C'\fR. Option \fB\-\-verbose\fR can be used
 to explicitly enable progress messages on \f(CW\*(C`stderr\*(C'\fR. By default, \fBrc\fR
 automatically determines whether progress messages should be displayed
 or not depending on whether \f(CW\*(C`stderr\*(C'\fR is connected to a terminal device.
 Option \fB\-\-keep\fR can be used for debugging purposes to keep the
 temporary files were generated during internal processing. Option
 \&\fB\-\-define\fR can be used to on-the-fly re-define a configuration variable
 \&\fIname\fR with \fIvalue\fR.

 .IX Item "@l_prefix@/bin/openpkg rc -p|--print package command [command ...]"
 \&\fBRun-Command Printing.\fR This is like the run-command execution (see
 above), but instead of immediately executing all involved individual
 run-command scripts, they are concatenated (but with all configuration
 parts reduced to a single configuration part) and printed to \f(CW\*(C`stdout\*(C'\fR.
 Use this for debugging or post-processing purposes.

 .IX Item "eval `@l_prefix@/bin/openpkg rc -e|--eval package command [command ...]`"
 \&\fBRun-Command Evaluation.\fR This is like the run-command execution
 (see above), but the resulting exported shell environment variables
 are output to a temporary file as a (Bourne-Shell or C\-Shell syntax)
 shell script, suitable for evaluation within the shell environment
 of the caller. A one-line script is printed to \f(CW\*(C`stdout\*(C'\fR which then
 \&\*(L"sources\*(R" (and immediately removes) this temporary file. This is
 slightly different from printing the temporary script directly to
 \&\f(CW\*(C`stdout\*(C'\fR, because not all shell implementations like to "\fBeval\fR\*(L"
 large multi-line scripts. Hence, use this for executing the \*(R"\f(CW\*(C`env\*(C'\fR"
 run-commands within the current shell.

 \&\fBConfiguration Variable Querying.\fR This queries the effective values
 (see \fBRUN-COMMAND \s-1CONFIGURATION\s0\fR section below) of one or more
 run-command configuration \fIvariable\fRs. Use this within a shell script
 to selectively query a particular variable.

 The foundation of the \fBOpenPKG\fR run-command facility are the individual
 run-command files \f(CW\*(C`rc.*\*(C'\fR of the installed packages. They are all
 located in the directory \f(CW\*(C`@l_prefix@/bin/openpkg rc.d/\*(C'\fR and are named
 "\f(CW\*(C`rc.\*(C'\fR\fIpackage\fR\*(L". They consist of one or more sections, each starting
 with a section header \*(R"\f(CW\*(C`%\*(C'\fR\fIname\fR [\fIoptions\fR]" and following a \s-1GNU\s0
 Bash compatible shell script. There are three classes of sections:
 .IP "\fBSpecial Sections\fR" 4

 There are 2 sections which have a special meaning to the \fBrc\fR program
 and cannot be used for different purposes.
 .RS 4
 .ie n .IP "%config" 4

 .IX Item "%config"
 This section has to consist of run-command configuration
 variable default settings in Bourne-Shell syntax only, i.e.,
 it has to contain one or more lines, each of exactly the form
 "\fIpackage\fR\f(CW\*(C`_\*(C'\fR\fIvariable\fR\f(CW\*(C`=\*(C'\fR\fIvalue\fR\*(L". Notice that in section
 \&\*(R"\f(CW%config\fR\*(L" of run-command file \*(R"\f(CW\*(C`rc.foo\*(C'\fR\*(L" the variables all have
 to be prefixed (by convention) with \*(R"\f(CW\*(C`foo_\*(C'\fR". It is allowed that the
 \&\fIvalue\fRs reference other variables defined before in the same section
 or from the "\f(CW%config\fR\*(L" section of the bootstrap package \*(R"\f(CW\*(C`openpkg\*(C'\fR".
 Additionally, by convention all lines have to be indented by 4 spaces.

 .IP "\fBConventional Sections\fR" 4
 .IX Item "Conventional Sections"
 There are 9 sections which have no special meaning to the \fBrc\fR program,
 but are used in \fBOpenPKG\fR by convention for standard purposes. Hence,
 do not use them for arbitrary things instead.
 .Sp
 Throughout these sections it is possible to specify the user to be
 switched to before the code is executed.
 .Sp
 A priority can be given for each section to control execution sequence
 if "\f(CW\*(C`all\*(C'\fR" packages are given. Higher priority leads to earlier
 starting and later stopping. The priority is a number where low numbers
 mean high priority (numerically sorted for starting). If omitted, the
 priority defaults to 500.
 .Sp
 Output generated on \fIstdout\fR and \fIstderr\fR is captured and normally
 suppressed. In case the sections script exits with a non-zero return
 value, the intercepted messages are consolidated, reformatted with a
 surrounding ASCII-art border and printed to \fIstderr\fR. If the section
 is tagged with option \fB\-o\fR, \fIstdout\fR messages are passed through
 verbatim, even if the section script exists with a zero return value.

 The file \f(CW\*(C`@l_prefix@/bin/openpkg rc.func\*(C'\fR is prepended to the scripts of all
 executed run-command sections and provides reusable functions.
 Currently the following functions are defined:
 .IP "\fBrcMsg\fR [\fB\-e\fR] [\fB\-w\fR] \fImessage\fR" 4
 .IX Item "rcMsg [-e] [-w] message"
 Print a message to the output device of the run-command caller. The
 message is printed to the captured \fIstderr\fR (but are visible to
 the caller of the run-command script only if the script fails). All
 messages are prefixed with "\f(CW\*(C`rc:\*(C'\fR". If option \fB\-e\fR is given, the
 prefix is "\f(CW\*(C`rc:ERROR:\*(C'\fR". If option \fB\-w\fR is given, the prefix is
 "\f(CW\*(C`rc:WARNING:\*(C'\fR".

 Add (option \fB\-a\fR) or remove (option \fB\-r\fR) one or more \fIdir\fRectories
 to/from the colon-separated value of a \fIvar\fRable. By default, on
 addition, the directory is appended to the end, if option \fB\-p\fR is used
 the directory is prepended to the start. If option \fB\-e\fR is used, the
 directories are added only if they exist on the underlying filesystem.
 Use this function for conveniently manipulating \f(CW\*(C`PATH\*(C'\fR, \f(CW\*(C`MANPATH\*(C'\fR,
 \&\f(CW\*(C`INFOPATH\*(C'\fR, \f(CW\*(C`LD_LIBRARY_PATH\*(C'\fR and similar variables.
 .IP "\fBrcTmp\fR [\fB\-i\fR] [\fB\-f\fR] [\fB\-n\fR \fIname\fR] [\fB\-k\fR]" 4
 .IX Item "rcTmp [-i] [-f] [-n name] [-k]"
 Convenience interface to secure temporary file handling. Option \fB\-i\fR
 first has to be used to initialize a secure temporary directory (option
 \&\fB\-k\fR later will kill this again). Under option \fB\-f\fR you then can get
 reasonable temporary filenames under the created temporary directory. By
 default, the temporary filename is just "\f(CW\*(C`tmp\*(C'\fR", but can be specified
 with option \fB\-n\fR to be \fIname\fR.
 .IP "\fBrcService\fR \fIpackage\fR \fIstatus\fR \fIvalue\fR" 4
 .IX Item "rcService package status value"
 Convenience interface to checking the \f(CW%status\fR variables
 \&\fIpackage\fR\f(CW\*(C`_\*(C'\fR\fIstatus\fR which have to be provided by the \f(CW%config\fR (if
 \&\fIstatus\fR is "\f(CW\*(C`enable\*(C'\fR" this is enough) and \f(CW%status\fR (if \fIstatus\fR is
 "\f(CW\*(C`enable\*(C'\fR\*(L", \*(R"\f(CW\*(C`usable\*(C'\fR\*(L" and \*(R"\f(CW\*(C`active\*(C'\fR"). The \fBrcService\fR especially
 caches the resolving of the variable values. Returns 0 if the resolved
 value is \fIvalue\fR, else returns 1.
 .IP "\fBrcVarIsYes\fR \fIname\fR" 4
 .IX Item "rcVarIsYes name"
 Checks whether variable \fIname\fR has a value of "\f(CW\*(C`yes\*(C'\fR\*(L", \*(R"\f(CW\*(C`true\*(C'\fR\*(L",
 \&\*(R"\f(CW\*(C`on\*(C'\fR\*(L", or \*(R"\f(CW1\fR" (with arbitrary lower or upper case letters). Returns
 if value is one of these positive ones, else returns 1.

 The \fBOpenPKG\fR run-command facility consisting of the scripts \f(CW\*(C`rc\*(C'\fR
 and \f(CW\*(C`rc.func\*(C'\fR were originally invented in November 2000 by Ralf S.
 Engelschall for \fBOpenPKG\fR. They were completely worked off from scratch
 in July 2003 for \fBOpenPKG 1.3\fR.
