There are a few HW products which allow write protection, you can find them 
in the archives. One SW solution which IMHO is pretty attractive is to 
remove the IDE modules from the kernel and the /boot/modules directory at 
the end of the init process. This requires the installation of new modules 
before anything can be done to the IDE devices.

 When you do this, there is no problem running fdisk, increasing the
size of the partition to the whole card, then running resize2fs to make
the filesystem use the whole 16MB.

 I've been playing with Pebble too; it's a Debian distro that seems to
run quite happily on a read-only 64MB CF card. Though as soon as I used
APT to install my first package (quagga, which also pulled in net-snmp)
it filled up & broke, so I'm now using 128MB CF cards. I think for my
needs Pebble may be the way to go in the long term, but we'll see.

 Originally, the way we did it was by having a /var as tmpfs, and when
something touched /var/run/sync.flag, every file in "important" folders
in /var were rsynced to /etc/var on the CF card. So, you could play
around with the config, firewall yourself out, and just hit "reset", and
you would be back to where you started. 

 There are loads of ways of doing it, but for our purposes (box intended
for linux newbies who used a web interface), it suited us.

Depends on the hardware/disks, I was just indicating that I wouldn't 
guarantee this process to work on 90% of available hardware rather 
than saying that it wouldn't work much/most of the time.

 I think it'll work, depending on how the IDE interface reports back the
CHS settings. We had great fun even on different models of 64MB cards -
some are 6.4e+7 some are 1024*1024*64 - some are a mix of the two.

 But, you could just add something to query the size of the CF in the
machine first. That script was part of a read-only CF based distro that
was built every night from SRPMs and CVS, so it had to be very
automated.

It makes since if you are using the same CF card and the specs can be 
assumed. However if the size/setup of the cards are not exactly the
same, you have a huge problem. Floppies are a safe assumption to 'dd'
to, but 8M,16M,32M,64M,... CF's are generally not. What kind of surprise

2003-10-30 Thread Jaime Nebrera Herrera
  Hi John,

>  Does anyone have LEAF images that can be 'dd' onto a CF card? What size
> ones are needed ?

  Lince is just a branch of Bering that makes it easier to install it in 
devices bigger than a floppy. In our case we developed it preciselly to run 
in a CF. You just need to install Quagga.

  Just follow the installer and should install in a CF. We are working on a 
quite improved release, based on cramfs and with some updates applied (newer 
kernel and so on). Actually we have it ready, we have just not made it public 
for the GUI to be ready for real usage (testing it right now).

  As allways the core system will be GPL and available in SF, but the GUI will 
be closed source. The core can work without the GUI as allways.

  So our next steps regarding Lince willl be:

  1) Finish GUI tests (almost done)
  2) Release image and GUI for paying customers
  3) Sell preinstalled Lince (with or without GUI) boxes based on embedded 
system.  
  4) A bit later release GPL lince core in SF (you can pay for GUI later on if 
you want to)
  5) Give VAR members of this list the chance to buy OEM and branded versions 
of the GUI and the box.

  So for those of you that want to be in a complete GPL side, you will allways 
have the choice to go to SF and download it. We will give part of our sales 
to the members of the Leaf team to contribute in the development of the GPL 
core (besides contributing code ourselves)

  You can see a screenshot of the GUI here:

http://www.eneotecnologia.com/pantallazolince.png

  You can see pictures of the box here:

http://www.eneotecnologia.com/soho_fotos.html

  Sorry, there is no more information on the website as we are just preparing 
to start this process.

 Where hda1 was to be a 2M "rescue" partition, with the kernel, and
enough smarts to download a new hda2 if stuff broke. Quite cute, really.
We had the OS changed to run the flash read-only (/var was tmpfs, synced
with an archive in / intermittently).

 And ta-da, you have a bootable 64MB image that can be put on a flash
card with "dd". No messing with tarballs etc. and it compresses really
well if there aren't 64MB of files on it. I'd like to something like
that for leaf, if there was interest. I need it for some quagga-based
routers I'm building anyway. I'm still hunting down the bits & pieces I
need, but if someone had a tarball of LEAF with working quagga binaries,
that would be a start.

 Zebra has pretty much stopped being developed; the guys who submitted
loads of ignored patches forked it, and got development up & running. I
think there are something like 1300 unfixed bugs in Zebra, compared to
Quagga. The guys that were working on Zebra concentrated more on ZebOS,
the commerical version.

 So say the guys on www.quagga.net, and seeing as they are still
releasing, I'm tempted to believe them.

be careful 'dd'ing images to a flash disk.  it's kinda easy to trash the
boot block, and it's rather a long road to fix that.

I have found in my use of CF disks the easiest thing to do is syslinux
-s the CF disk and then blow apart the image and copy the lrps,kernel,
and boot config files directly on it.  This works wonderfully.  Boot
times are around 5 seconds.  backing up packages is really fast.  Only
problem I have right now is no write blocking without physical access to
the box and opening it up.

 I'm looking to have a LEAF box running Quagga (the forked version of
Zebra), and CF would be a lot nicer than a floppy.
Typically, you don't 'dd' an image onto a CF card.  You would normally 
treat the CF card as a hard-disk.  Once you partition & format a 
suitable area of the CF card, you can copy the syslinux boot-loader and 
the files that make up the LEAF distribution you want to use.

If you're not real familiar with using CF cards, you may want to get 
plain 'ole DOS booting off of it first, to make sure you've properly 
formatted your CF card, configured your BIOS, etc.  Then you can get 
LEAF running, and you can be pretty sure any problems you encounter need 
to be solved on the linux side.

Normally, the main thing you'll need to tweak is the kernel command line 
(to tell LEAF where to find it's packages, since you're not booting off 
the floppy disk), and possibly load the proper drivers for your CF card 
(typically just the IDE drivers, if they're not compiled into the 
kernel).  The instruction for installing your chosen LEAF varient (I 
suggest Bering) on a hard-disk are a good starting point, and you can 
post to the list if you run into any problems.

[leaf-user] LEAF on compact flash

2003-10-29 Thread John P. Looney

 Does anyone have LEAF images that can be 'dd' onto a CF card? What size
ones are needed ?

 I'm looking to have a LEAF box running Quagga (the forked version of
Zebra), and CF would be a lot nicer than a floppy.
