Reflashing the device is a fine thing, but it's rather annoying to  
reinstall all the stuff back, so before doing anything I prefer to ask  
here:
provided I have everything installed the "normal" way (on the internal  
memory: not used the trick of extending the root filesystem on the MMC),  
is it possible to flash the device and re-set it up like it was before  
reflashing, without having to re-install everything manually?

So, let's say, is it possible to backup some directories and files via  
ssh, flash the device, reinstall the ssh server and write the backed up  
stuff into the flashed device, in order to have everything working again  
with minimum effort? If yes, can someone write a list of the dirs/files to  
include (or exclude) in the backup in order to accomplish this task? It  
seems linux is rather good for this kind of things, but I don't know well  
what to backup'n'overwrite after the reflash and what to exclude, so wise  
advice here is really appreciated. It would be nice a command to tar all  
the stuff needed directly from the device to the PC via ssh (the "backup"  
step), if that's possible, and the corresponding reverse command for the  
"restore" step.
