Why can't I save/restore block devices?

No, don't have the space. And btw, why should I copy a perfectly seekable 
device to a file just to compare it? And afterwards copy the modified file 
back onto the partition?
Sorry, no.

I think it would suffice to change the check IS_REG() in generator.c and get 
the size not from stat() but from ioctl(GETBLKSIZE) [?]
After all, a block device is nothing but a big file :-)
