Now that /dev/urandom and /dev/zero can be used by all applets
there's no need to mention that dd has support for them.

dd: add support for writing to physical drives2024-08-02T07:41:25+00:00Ron Yorstonrmy@pobox.com2024-08-02T07:41:25+00:00urn:sha1:dab0de7dbe833a44b3e4c20fcd0044f2d878d10d
A common use of 'dd' is to copy boot images to removable media.
This didn't work on Windows because opening a physical drive
failed with the default flags used by 'dd'.
If the output file is a physical drive remove incompatible flags.
Writing to a physical drive requires elevated privileges and the
drive must be offline.
Adds 80 bytes.
(GitHub issue #435)
