| Hello again,
| 
| I've got the thing running, but the images are 256MB but I've only
| managed to get the "used" space down to around 80MB.
| 
| I was hoping is there anything in the configuration file to get it
| down to bare bones and slowly add things in. Is it possible to get it
| down to pretty much a kernel + shell?
| 
| My config file is

Mine is (it was for a 6.1-PRERELEASE though)

The resulting fits on a 64Mo flash :
/dev/ad0s1a     57M     52M    4.7M    92%    /
/dev/ad0s3     1.8M    116K    1.7M     6%    /cfg

I was planning to upgrade my soekris to 6.2, I'll try to see if it still fits
:)
