barry allen inner workings

[speertje]

Hi everyone, does anyone know the inner workings of the barry allen plugin?
I'm trying to get it to only use the usb stick, but it seems to spin up the hdd now and again.
Thnx!

when barryallen is being installed it will look for
1st cf card
2nd usb
3rd hdd

it cant be seeing your usb and going straight to the hdd
your usb may not be formatted right
oh what box you using

I have a DM800 with Nabilo Pure Flash and latest Bary Allen.
BA installs to USB. ( at least it tells me it feels at home in /dev/scsi bla bla bla/ part1 ( which is the usb.)

Then I use Nabilo blackhole 0.11 from /MB_Images ( links to /media/hdd/MB_images )
Where do the unpacked images go? to usb?
Have'nt checked /media/hdd/MB_images contents yet, couse I don't know the root password for this image. ( it is not "dreambox" )

Thanks. Eize

install barry allen via Nabilo Pure Flash image
what happends is when barryallen gets installed say to your usb stick
on your internal hdd it will create a folder called MB_IMAGES
this is were you ftp your image example "nabilo v0.11.nfi"

using Nabilo Pure Flash and latest Bary Allen.
then bring up barryallen menu via blue button
look for the option extract image from MB_IMAGES
then you will see the image you ftp,d there
it will extract your image to the usb stick
it should reboot the box
then back to Nabilo Pure Flash image
goto barryallen menu,s
there should be an option to boot extacted images (worded some thing like that )
then pick the extarcted image
it should reboot to your new image

Thanks westkill, for that.

I got it working allright, just wondered how this works.
I am a linux administrator ( RedHat ), and know how multiboot works there.

I was wondering how this 'plugin' works.

I think I've figured it out.

All images are extracted at /media/ba/ba/#imagename#
When bootprocess starts, instead of mounting /var /usr etc, it creates hardlinks to /media/ba/ba/#imagename#/var

This also means you can transfer your settings list between images, because they are just subdirs of /media/ba/ba.
( just do a find / -name "*whatyalookingfor*" -type f and it will show you the different 'versions' of the file, then simply copy between directory's )

Yes all this has sense. When I telnet to Dreambox after BarryAllen image has booted some image from CF i see /etc points inside /media/ba/ba.
Thank you for enlightening me.
