New Revision: 265132
URL: http://svnweb.freebsd.org/changeset/base/265132
Log:
Add a /dev/full device.
/dev/full is similar to /dev/zero except it always returns
ENOSPC when you attempt to write to it.
For some reason this reminded me of something I've been wanting for a
while but never get around to writing... /dev/ones, it's just
like /dev/zero except it returns 0xff bytes. Useful for dd'ing to wipe
out flash-based media.
Surely for that you want camcontrol security ...?
Regards
Steve
