This is for FreeBSD to turn off use of the CLFLUSH instruction via the
hw.clflush_disable loader var. We have encountered some opteron machines
on which this causes problems.

The attribute can be set for the node_type (via the web page for editing
node types) or the node (via brute-force SQL hackary) to override whatever
FreeBSD would do by default. This attribute is passed via tmcd to the
diskloader MFS which will fixup the loader.conf file post-frisbee.

* The httpd.conf file I started with came from Dave's linux-port branch,
  and subsequently whacked for FreeBSD installation. Sorry for not using
  git to bring the base version in.

* Configure changes to determine what version of apache is installed, and
  modify behaviour in makefiles accordingly.

* Along with Apache 2.2 comes the latest version of PHP5, and that requires
  a bogus timezone directive in php.ini to prevent endless warnings. So I
  moved the entire php,ini install from ops/boss-install to here.

Note that I had to use the 8.2 ports tree to build this stuff, and it the
usual headache cause options and directives have changed.

Newer PHP complains if you don't explicitly set your timezone, so this script
allows us to determine it in a scriptable way as part of {boss,ops}_install.

You would think this info would be readily available, but I couldn't find an
easy way!

to use this with -n (impotent) option! Useful for debugging and
testing when there are not nodes free for many days at a time.

Also update the DONE status on a few things.

On Linux, device IO goes through the buffer cache by default. This makes
frisbee run really fast...until it closes the output device. Then it sits
for minutes while it flushes disk data out of the cache. This is
technically okay, but wasteful, since frisbee allocates its own memory
for caching disk write data. By using direct IO on the output device,
writes do not go through the cache.

Aren't two caches better than one? No. They can compete for memory and it
just causes an extra data copy. Frisbee is faster when using O_DIRECT.

Note that this change is complicated somewhat because Linux requires that
the IO buffer for an O_DIRECT opened file be sector aligned. So we play
some games to do this.

This should have no effect on FreeBSD where device writes don't go through
the buffer cache.

part of an upcoming change to make Trunk links explicit in the DB.

Wait til all other threads have joined.

It is possible for USERNODE and FSNODE to be set differently but still be
the same machine (we do it, and our defs-default file shows it). This will
badly mess up your ops install. So use the _IP settings instead.

ports) we noticed that there was an incompatible change in
p5-RPC-XML-0.65 (from 7.2) and -0.76 (from 8.2).

Formerly, RPC::XML::Parser() was OK with parsing only suitably
encoded arguments rather than entire MethodRequest or MethodResponse;
now it throws an error.

We've tested the following (2 + 1) line patches on FreeBSD7.2 and
know them to be backwards compatibile there, and highly suspect it will
be OK for 6.3, although we don't have the means of generating a 6.3
e-in-e anymore.

Added a '-Z' option to ptopgen to force old version.
Added '-z' (force new ptopgen) and '-Z' (force old ptopgen) options to mapper.

Previously, distinguishing between node-node and node-switch direct links had
been done implicitly by using (null) interfaces as a magic value. We can't
do that any more now that switches have proper interfaces.

Added query count printout when debug flag is set.

It is now only 1/3 slower than the original. The price of modularity. *sigh*

ptopgen_new is now merely twice as slow as the original.
