[snip] @Phil and Brian: Can you please have a look? This is really trivial and easy to test. It is mostly about not erasing RAM drives when printing their partitions. Thanks in advance! Test: modprobe brd dd if=/dev/urandom of=/dev/ram0 bs=1M count=1 dd if=/dev/ram0 | xxd | less # see random data parted -s /dev/ram0 p # zeros the device with BLKFLSBUF ioctl dd if=/dev/ram0 | xxd | less # see zeroed data Cheers, Sebastian
