which installs to ${RCD_SCRIPTS_EXAMPLEDIR}. But the MESSAGE
referred to wrong hard-coded location if the RCD_SCRIPTS_EXAMPLEDIR
was not the default. So use RCD_SCRIPTS_EXAMPLEDIR instead.
PKGREVISION not bumped because if someone had changed
RCD_SCRIPTS_EXAMPLEDIR before recent change of autoregistration
of rc.d script in PLIST, then it could not have been packaged
in first place.
Note that this commit does not imply that the MESSAGE is correct.
In some cases, the MESSAGE is clearly wrong such as suggesting
running the rc.d script from the example directory (which will work
although).
the RCD_SCRIPTS rc.d script(s) to the PLIST.
This GENERATE_PLIST idea is part of Greg A. Woods'
PR #22954.
This helps when the RC_SCRIPTS are installed to
a different ${RCD_SCRIPTS_EXAMPLEDIR}. (Later,
the default RCD_SCRIPTS_EXAMPLEDIR will be changed
to be more clear that they are the examples.)
These patches also remove the etc/rc.d/ scripts from PLISTs
(of packages that use RCD_SCRIPTS). (This also removes
now unused references from openssh* makefiles. Note that
qmail package has not been changed yet.)
I have been doing automatic PLIST registration for RC_SCRIPTS
for over a year. Not all of these packages have been tested,
but many have been tested and used.
Somethings maybe to do:
- a few packages still manually install the rc.d scripts to
hard-coded etc/rc.d. These need to be fixed.
- maybe remove from mk/${OPSYS}.pkg.dist mtree specifications too.
While here, convert to buildlink3.

Changes:
The main purpose of this release is a stable target with many fragroute
and tcp connection oriented fixes. This is also the last release of the
1.8.7 line and signals the start of the beta cycle for the 1.9 branch.
<mipam@ibb.net>. From the release notes:
1.8.4 and 1.8.5 both had bugs that were found right as we were ready
to do a full release and represented good midway points but 1.8.6
should be the stable target.
Changes include:
* The ICMP decoders have been rewritten.
* (This is a summary of recent changes -- not all mine)
* Fixed stream4 offset initialization
* Double Open of snort log file
* Lots of new rules
* Fatal error on problems other than -> and <>
* Fixed stream4 several low memory conditions
* Error checking in stream4/frag2 argument parsing
* snort-db schema updates to 1.05
* --with-pcap-includes should now look at specified pcap
* packet statistics now should be more accurate with regards to lost
frags
* double PID file write
* S4 alignment problems on SPARC fixed ( rpc_decode still has SPARC
alignment errors )
* new snmptrap code
* documentation updates
* Stability fixes in frag2
* SEQ / ACK checking should be correct
* Reassembled packets with stream4 will now also be inspected when
using -z est
* ip fragments are now calculated correctly
* rule headers correctly matched
( multiple CIDR performance greatly increased )
private mail -- thanks!)

Major repairs include a fix to frag2 on Linux platforms, the icmp
decoder and printout routines were updated to match the data
structures that I implemented in 1.8.1 and the flexresp code was
repaired and should now be faster, plus the usual rule updates. I
also added a new "-B" command line switch to convert IP addresses
in a pcap file to a new specified IP subnet addresses.

a signal
* fixed PID path generation code, PID files go in the right place
now

* fixed stability problems in frag2
* tweaks to spo_unified for better integration with barnyard
* added -f switch to turn off fflush() calls in binary logging mode
* added new config keyword to stream4, "log_flushed_streams", which
causes all buffered packets in the stream reassembler for that
session to be logged in the event of an event on that stream
(must be used in conjunction with spo_log_tcpdump)
* added packet precacheing for flexresp TCP packets, responses
should be generated more quickly
* fixed rules parser code for various failure modes
* several new rules files and a new classification system
* SNMP alerts
* IDMEF XML output (the Silicon Defense plugin is integrated into
the main codebase now)

filenames conform
* to the data in the documentation
* Revamped the ICMP data structures to mimic those found in *BSD
and provide for higher fidelity decoding/printout in the future

* For the record, the payload dump conforms to the length of the IP
datagram now and does not show pad bytes added by the minimum
Ethernet frame size
* Applied Chris Cramer's byte ordering patch to the flexresp code
