# Argh! dhclient in FreeBSD 5 has a new auto-background "feature",
# it dives into the background after 10 seconds regardless of whether
# it has received a response.  This is fubar for us.  Unfortunately,
# we cannot just crank this number through the roof because it is based
# on a polling interval which actually has a rational purpose.  The timeout
# is actually (2 * polling_interval) where polling_interval is how often
# dhclient rechecks an interface without link.  We need to keep this value
# reasonable in the event that we boot up and don't immediately have link
# on the control net.  So lets try 15 seconds (30 second auto-background
# timeout) and see how things go.

So modify my previous hack to look for the first instance of a label=
in that case.

This hack has now officially transcended Plain Ole Ugly and has entered
the realm of Butt Ugly.

groklilo when setting root device

with ugly "undefined variable" messages in the log.  Futureproof the
initialization.

Remove the RHL90-specific delaysetup script.  It's now common, existing
only in the 'linux' subdir.

Added delaysetup with fixed paths for RHL90

in FreeBSD 5.  Whatever slice you want to apply the DIOCSMBR to, has to be
open RW.

(5.4 requires a different emulab-fs package due to some dangling shared
library reference).  It was easier to build a new package than to track
down the dependency (and you know how easy building a new package is!)

Entailed new instructions for manual setup as well as integration into
elabinelab framework.  First, the manual path:

setup.txt, setup-boss.txt, setup-ops.txt and new setup-fs.txt:
    Updated to reflect potential for separate fs node.  The org here
    is a little dicey and could be confusing with ops+fs vs. ops and fs.
    Has not been field tested yet.

*/GNUmakefile.in: new fs-install target.

configure, configure.in, defs-*:
    Somewhat unrelated, make min uid/gid to use be a defs setting.
    Also add config of fs-install.in script.

boss-install.in, ops-install.in and new fs-install.in:
    Handle distinct fs node.  If you have one, fs-install is run before
    ops-install.  All scripts rely on the defs file settings of FSNODE
    and USERNODE to determine if the fs node is seperate.

utils/checkquota.in:
    Just return "ok" if quotas are not used (i.e., if defs file FS_WITH_QUOTA
    string is null.

install/ports/emulab-fs:
    Meta port for fs node specific stuff.  Also a patch for the samba port
    Makefile so it doesn't drag in CUPs, etc.  Note that the current samba
    port Makefile has this change, I am just backporting to our version.

Elabinelab specific changes:

elabinelab-withfs.ns:
    NS fragment used in conjunction with
	tb-elab-in-elab-topology "withfs"
    to setup inner-elab with fs node.

elabinelab.ns:
    The hard work on the boss side.  Recognize seperate-fs config and handle
    running of rc.mkelab on that node.  fs setup happens before ops setup.

rc.mkelab:
    The hard work on the client side.  Recognize FsNode setup as well as
    differentiate ops+fs from ops setup.

Related stuff either not part of the repo or checked in previously:
    emulab-fs package

	'boss' -> 'boss+router'
	'ops'  -> 'ops+fs'
	'fs'      (new role)
	'router'  (new role)

These are in preparation for allowing configurations with split ops and fs
nodes (and sometime down the road, split boss and router nodes).

This checkin is just the DB state changes along with the scripts that look
at that state.  The Big One, which actually sets up separate nodes
automatically, is undergoing more testing but will be Coming Soon.

but "prepare" is the script that goes in the tftpboot directory on boss.

If unlink fails, do chflags and try again.

Bring linktest in line with the new event system world order and do some
generic cleanup.  I'm pretty sure I broke backwards compatibility with
old disk images though...

	* configure, configure.in: Remove linktest.h.in from the list of
	template files.

	* event/linktest/GNUmakefile.in: Don't make subdirectories for
	executables since it can mess up the dependencies.  Don't install
	tb_compat.tcl stuff anymore.  Check for '/usr/local/bin/pathrate'
	and friends, and print out a warning if they are not found.  Make
	a version file for the linktest daemon.

	* event/linktest/linktest.c: Only subscribe to the events we care
	about 'STOP/KILL'.  Subscribe to TIME START events and kill any
	linktests that are in progress.  Send events through the local
	elvind instead of running tevc.

	* event/linktest/linktest.pl.in: Don't run the modified NS anymore
	to generate the topology file, use gentopofile to do that.  Send
	COMPLETE events to indicate that the tests were finished instead
	of STOP so it works with event-sequences.  Use emulab-sync to
	report errors between linktest daemons.  In addition to sending
	REPORT events, send LOG events to the SIMULATOR agent so the
	messages end up in the report e-mail.  Fix wait_all so it collects
	child processes immediately and doesn't leave zombies lying
	around.  Make the static route test work with topologies that
	aren't fully connected.  Change ownership of the linktest error
	files from root to the swapper.  Bump latency tolerance up to
	2.5ms.

	* event/linktest/ltevent.c: Use event_schedule instead of
	event_notify so the events go through the scheduler.

	* event/linktest/run_linktest.pl.in: Wait for COMPLETE events
	insetad of STOPs.

	* event/linktest/linktest.h.in: Removed.

	* event/sched/error-record.c: Include linktest error output in the
	report e-mail.

	* event/sched/event-sched.c: Linktest now sends COMPLETE events
	for START events.

	* tbsetup/gentopofile.in, tmcd/common/config/rc.topomap: Piggy
	back the generation and management of the linktest config file
	onto the generation of the topomap.

	* tbsetup/ns2ir/sim.tcl.in: Add "linktest" event to the Simulator
	object that runs linktest at level 3 (latency, static routing, and
	loss).

	* tmcd/common/libsetup.pm: Add TMLTMAP constant that contains the
	path to the node local linktest config file.

	* tmcd/common/rc.linktest: Pass '-u' option to the linktest daemon
	so it knows what user should to change ownership of files to.

	* tmcd/freebsd/jail/mkjail.pl: Copy the linktest config file
	(ltmap) into the jail.

for the server to reboot us.  This avoids a race condition that occurs
under load (see the comment in the code).

the 'one-true-awk' version of awk, botches the calculations when the
values get close to MAXINT.  Instead, just create a hex string since
sysctl knows about hex numbers.
