dd dies on SIGUSR1

[Chris Rees]

Hi all,

Does anyone have any thoughts on [1]?


It's a common usage in GNU systems to send SIGUSR1 to dd, which causes
it to print info. However... when I tried it it died (ouch).

Two patches are in the PR, one to print summary (imitate GNU) and
after talking to gavin@ on #bsdcode I made one to ignore the signal.

Which one of these fixes will be most popular?
