thanks Dave... will look into the overlay file system + kernel hack soun..

got the 9front booting off one 9660 drive now (50GB) and am 

mounting my second 20GB drive into /tmp/D (its a 9fat partition)

and i have rebooted and the created D files are still there

one strange thing that bogged me down for most of today (and stopped

me emailing you earlier), was that I edited the .iso, lets call it cwCON.iso 

and catted that to /dev/sdC0/data and no matter what I did it would not boot,

the fs was there, but no booting...

what I am after doing is reverting to the current 9front iso just 20 mins

ago and it worked perfectly, so somehow they created 3 partitions 

in /dev/sdC0/data (a 486MB, a 1MB ESP (1 cylinder) 

and another large file system) (using cat???) so... my next post is 

going to wonder how they did that and how i can add some handy

scripts to my own version of their iso... (is /386/pbslba somethingp...) 

ps: is a 20GB file system safe? r why should i use fossil??

Kind Regards... & happy summer Dave... /c@midnight+43mi
