Dear sirs:
I send you a bug report.
# DESCRIPTION
Bug in dd: it sends wrong messages to stderr.
For example, when I do backups, I see "errors" from dd... that really aren't.
# WAY TO REPRODUCE THE BUG
A user can execute:
partition=$(mount | awk '$2=="on" && $3=="/" {print $1}')
sudo dd if="$partition" of=/tmp/copseg.dd count=1 bs=512 >/dev/null
and then he sees something like this in his screen:
1+0 records in
1+0 records out
512 bytes (512 B) copied, 0,000129625 s, 3,9 MB/s
# EXPECTED RESULTS:
The user should see nothing, as there was no error and stdout was redirected
to /dev/null.
