happens when tbprerun does its thing. Causes experiment creation to
stop, when using delay nodes.

fix at some point.

next_boot_path so that OSKit-NETBOOT.SILENT does the right thing.
This gets pulled from the disk_images table. Temporary though, since
we want to allow more flexibility in how the OS and related stuff
gets specified.

mkacct-ctrl: fixed the EUID/UID problem; removed all su1s from
'su1 ssh' calls.

tbrun.tcl: added call to mkacct.

rmacct: added a die if we fail to open uname pipe.

are checked against the disk_images table. There is not dnard support
and no create-os support.

(nodes that were allocated) so that subsequent runs don't run out
of resources. Not appropriate to force user to run tbend on failure.

checking, database queries and machine-pinging is done, i set
the UID = EUID for the remaining root-only commands. Cleaned up
the su1s from the commands as now they're unnecessary (and wouldn't
have worked for non-su1-able users, anyway).

I tested this as user tu1 - one of my test users with no
privileges (i set tu1's shell temporarily to tcsh) on paper. its
a good thing because this revealed some  typos in my queries for
the non-privileged-user path. Fixed those.

Still need to deal with "stop" button.

the same. Added chown/chmod lines in the post-install section.

rmuser call to 'pw userdel'. added call to killtip.

appropriate for the node type). This prevents the user from editing
the IR file directly and specifying a bogus image ID.

checks to make sure that the OS image that has been specified in the
IR file is valid. Need a database check for this. Also, no delta stuff
yet; just the main OS partitions that are know to exist on the disk
already. Guess we also need to worry about reloading the disk from this
script. Sigh, still lots to do, but this will be okay for a little while.

like os_setup and delay_setup.
Change exitcode to return zero on success, or non-zero number of nodes
that failed.

Complete re-write. This version will be easier
to maintain and less likely to break. Turns out that in
addition to being cleaner, the script runs about 5 times faster
because we open many fewer remote pipes.

An example of what was modified:

To create a user in the old version:
	- open up a local file
	- dynamically generate a script of chpass calls for
		new user accounts and dump into above file
	- scp over the file
	- source it remotely via ssh

And now:
	- ssh pw
	- ssh chpass (turns out i couldn't use dave's usermod
	   example because usermod takes an unencrypted password)

their experiments, via the experiment information page.

Noticed that I had a hard-coded test value still in the code ('lkwbox'
instead of $project; fixed that. Took out inclusion of Open2 package. Allow
a dash into the project name verification.

who have real shells on paper.

'cd <dir> ; command' (this is the only cirumstance where
these characters, or 'chained comands' are allowed). This
was done so that the wrapper script can use it, so that
the wrapper will work properly for people who have real
shells on paper.

webserver, as the uid of the experimentor. Not fully debugged yet
since the testbed has been kinda broken all day, but this needs to get
in if anyone else works on it.

some more work (taint checking), and possibly a splitup. Maybe have the
parsing code in one place and actual rebooting code and the like in
another place.

Add a top level rules file with common stuff like install rules.
Beef up tbsetup makefile, and include above files. Add install of all
the tbsetup programs to the bin dir and to the bogus lib/tbsetup
directory.

project approval section.

current umask, and so I don't get the protection value I want.
Too lazy to go figure it out, and adding a chmod was easiest!

to run a setuid script, but in this case, we want to allow it. Actually,
I'm not entirely sure that this restriction makes sense in our semi
controlled environment, but better safe than sorry. If you think I'm being
too paranoid, let me know.

Program must exist in the testbed bin directory.

all the scripts send output.
Remove test for group writable directory (where program exists). Too
paranoid and too inconvenient for all of us since it would require root
installs all the time.
