Overwriting CRAMFS image while it is mounted
 
Dear all,

I am on a ARM9-based embedded linux system (kernel 2.6.22). My application is stored as a CRAMFS image on a NOR-flash partition. During system bootup this image get's mounted with the help of the loopback device and after that the application get's started.

Now I would like to be able to update the application during runtime. Is it generally safe to overwrite the CRAMFS-image while it is mounted?

Best regards and thanks for help,
Markus

I don't know, but I wouldn't have thought so. Have a look at this and this for some general background.
