Well yes and no. I agree it could be considered reasonable, but where
does the error from the DumpPreUserCmd go otherwise?
According to the manual it's supposed to be in the XferLog:
Stdout from these commands will be written to the Xfer (or Restore)
log file. One example of using these commands would be to shut down
and restart a database server, dump a database to files for backup, or
doing a snapshot of a share prior to a backup. Example:
$Conf{DumpPreUserCmd} = '$sshPath -q -x -l root $host /usr/bin/dumpMysql';
However this could have been written before
$Conf{UserCmdCheckStatus}
existed.
I make the claim that any output that is generated by a BackupPC_dump
command should be placed into the XferLOG (which is arguable misnamed
and could be BackupAttemptLOG but such is life).
