This is very useful, thank you. With this code I'm able to have two different 
fstab files under packages-split:
./packages-split/base-files-regular/etc/fstab
./packages-split/base-files-flash/etc/fstab

Regardless of that though, the resulting rpm packages for "base-files-regular" 
and "base-files-flash" have the original fstab as in "base-files", which is 
different to both the fstabs in packages-split mentioned above.

I'm looking at what might be causing this, but any idea is welcome.

Thanks,
Diego
