Hi, I recently started using udev and have used devfs in the past. When these are used the long internal kernel names for the block devices are shown, e.g. "/dev/ide/host0/bus0/target0/lun0/part1" instead of "/dev/hda1". These long names show up in df as well.
Once more than half a dozen devices are in the system, the readout is less easy to read, e.g. $ df -h Filesystem Size Used Avail Use% Mounted on /dev/ide/host0/bus0/target0/lun0/part5 19G 6.8G 12G 38% / /dev/ide/host0/bus0/target0/lun0/part6 82G 60G 22G 74% /mnt/store I have made a patch to add a --wide (-w) option to df, so that the "Filesystem" column has more space. Here is an example of its output:- (use fixed width font to see columns line up). $ ./df -w -h Filesystem Size Used Avail Use% Mounted on /dev/ide/host0/bus0/target0/lun0/part5 19G 6.8G 12G 38% / /dev/ide/host0/bus0/target0/lun0/part6 82G 60G 22G 74% /mnt/store It has enough space for scsi and part > 9, and does not break the other options.
