Writing to an read-only embedded linux system!!
 

hi,
I'm a newbie to embedded linux. I managed to compile and boot uClinux onto my custom processor board. But the system is read-only and I can't create a file of my own. I don't want to write to flash, but just write some script file temporarily. I remember reading something about writing to ram by mounting it somehow. Can anybody help me??

Well, yes, it's hard to write on a read only filesystem ;-))

You are probably looking for a ramdisk, like described here:

Maybe there is also a "Ramdisk on embedded systems" howto somewhere out there.
