Ok, I will look into.

Yepp, works like a charm, Thank you =)
My board have 128MB ram and 16MB flash.

No its another filesystem that I want to mount.

The root filesystem is inside the kernel image (MD_ROOT option) , the
kernel will mount from it (/dev/md0)
When the kernel image was generated I zipped it and stored it on the
flash, so a bootloader like Redboot will unzipp to ram and run the
kernel.
So I guess its messy to touch the filesystem that is inside a zipped
kernel image. Filesystem itself is not zipped.

So idea is to create another directory in the flash FIS (Flash Image
System) where I store new versions of somefiles. And your tar advice
works nicely, that makes it easier than having a filesystem on flash
and it will be zipped too!!!!! Thank you :)

Maybe no need to fidle with the flash driver and UFS code, who knows... :P
I guess ideal scenario is having a direct read/write separate
filesystem for some paths like /etc on the flash, while /var and /tmp
are mounted as /dev/mdX and the rest is read-only.

Thank you!
