Fun plug management

[Dwight Hubbard]

I finally got the bootloader I mentioned a while back written.  I had one idea I wanted to put out there.

That is adding a drop down menu to System->Utilities->Reboot to allow specifying the fun-plug to run on reboot.  I could just create a package for the funplug_manager that allows configuring the OS to reboot from it's configuration page but it seems like it would make more sense from a UI standpoint for it to be part of the System->Utilities page.

Looks fine to me.

The dropdown would only appear if
-the unity is not Alt-F flashed, using isflashed() from common.sh.
-the funplug_manager package is installed

The default funplug name to use should be stored in /etc/misc.conf,
and selected by default.

What do you think?

PS-Guess that isflashed is not yet in svn, and sys_utils*.cgi neither
(and has changed)

# returns true if Alt-F is flashed
isflashed() {
flashed_firmware=$(dd if=/dev/mtdblock2 ibs=64 count=1 2> /dev/
null | strings)
echo $flashed_firmware | grep -q Alt-F
}

I forgot to say: in this case the 2 minutes timeout is not needed,
right? Can the funplug_manager "boot" the right funplug without any
delay?

The default funplug that the funplug_manager will boot if nothing is selected funplug.d/default which is a symlink to the funplug script to run.  The selector just changes the link when a different fun plug is selected.  I could store a copy of the setting in /etc/misc.conf but it would seem to me to be easier to just have the cgi dereference the symlink instead of storing the info in 2 places.

I like the idea of a no-delay option.  That would be pretty simple to add, I could have the fun_plug script that calls the webserver skip running the web selector if there is a funplug.nodelay file.  Remove the funplug.nodelay file and immediately run the default fun_plug.

Ok, in the next version of the funplug_manager has been cleaned up a good deal.  Here is how to get funplug_manger
0.15 or newer to boot into a specific fun_plug script without delaying to prompt the user (replace /mnt/HD_a2 with
/mnt/sda2 as appropriate, oh and the nodelay file is deleted after use, so it's a one time thing):

touch /mnt/HD_a2/fun_plug.d/conf/nodelay
(cd /mnt/HD_a2/fun_plug.d/funplugs;rm default;ln -s "desiredfpscript" "default")

In the newest version the script fun_plug.d/bin/rebootinto does this.

The "signature" to see if the fun_plug manager is installed (by the
user) is if a "fun_plug.d" exists in the root of any of the mounted
filesystems, right?
That's because of the kernel enumeration and RAID exixtence, one does
not know if the "boot" device is in /mnt/sda2, or /mnt/md0, or even /
mnt/sdd2 (with two usb pens attached, and errors in one of them, it
happened to me once that the disks devices where sdc and sdd !).

Good question I currently search multiple directories for the fun_plug.d dirrctory (Don't recall all of them offhand)
