Hello, I've been working on implementing dmraid support in the Debian Installer, and have been using 'dmraid -s -c' to detect if any dmraid sets are present. Problem with that is that 'dmraid -s -c' will in at least two situations exit zero and display what for my purposes is effectively an error message on stdout: - no block devices found - No RAID disks Having to grep for these messages is of course not very clean, especially as I can't be sure to cover all possible conditions. Was there a particular reason why it was decided to exit 0 in those cases and direct those messages to stdout instead of stderr? Would it be an option to change this? Is there perhaps a better way to detect if any dmraid devices are present that does not suffer from this issue? An alternative I was thinking of myself is the following, but that is still not very clean: # dmraid -s -c r,t --sep "%" | grep "%" | cut -d% -f1 Thanks in advance, Frans Pop Debian Installer developer
