I'm reflashing OpenZaurus alot because I'm fiddling with packages and .deb files, and other things, and I need to be able to start clean so I don't accidentally give myself libraries and things without documenting that I installed them. Each time I reflash OpenZaurus, I'm noticing libraries and things from previous installs persist in the list of installed packages. Also, the username of the previous owner keeps showing up as a folder in / after each reflash. I'm not that familiar with the 5600's inner workings about where it backs things up/caches things/etc, so I'm obviously missing something when I reflash. I want to be able to completely zero the thing out. No previous information, no previous data, nothing. Just a clean OZ install. I've even tried flashing other roms, then flashing OZ back on over that. Same story. I've made sure the CF card I'm using for flasing is clean other than the OZ files, I'm dug thought the filesystem as best I could... What am I missing?

(Ignore the sig.. That's what I had about a year ago..)

The Poodle has two flash partitions: "/" (ie: the rootfs) and /home.

The rootfs is completely wiped on a reflash, /home stays untouched (which is intended).
Sounds like you should clean out your /home directory.

Almost correct. Replace the DOS pattern *.* with * and you are set.

What, the Zaurus? Yeah, death first. Supporting these things would SUCK. They're definitely not for the feint of heart or the non-tinkering type.
Ok I deleted the /home contents completely... Reflashing...

lol Actually, I have VERY few problems with XP. Anyway, clearing out /home did it. I now have a completely clean install of OZ 3.5.4. I still have two questions:

When OS 3.5.4.1 comes out at the end of the week, I'll just flash it without clearing out /home and that'll be it, right? No reinstalling apps, libraries, resetting settings, etc?

OZ uses DropBear instead of OpenSSH. How much smaller/more effecient is DropBear? One of the advantages I can see of going with OpenSSH instead is easy file transfers via sftp. What else? Any specific reasons why I SHOULDN'T use SSH instead?

Thanks!

That depends where you install the packages. If you were to install all additional apps into /home, then yes, that would survive a reflash but you'd have to run ipkg-link manually to relink the files from /home to /.

IIRC openssh adds about 1.5Mb to a base install.

There are many good reasons to use OpenSSH and no drawbacks compared to dropbear but its size.

I personally never use dropbear.

Where would be the best place to install things, if not /home?

If you have a ext2 or ext3 formated SD card you can install stuff there. You just need to leave the card in the slot all the time. I have all the important stuff in either / or /home and optional or large (python) programs on my SD card.

I hope this helps,
