(I.e. hardware where you can pull the medium out of the drive mechanism.) So in this sense, an USB attached HDD should actually not present itself as "removable" unless it's a SyQuest or Zip or something like that. Furthermore, if that's what the discussed bit stands for, than it is rather arbitrary to base a policy on it whether a volume may be mounted by non-root users or not. Rogério, perhaps static fstab entries based on /dev/disk/by-id/... can help. -- Stefan Richter -=====-==--= -=-= ==-=- http://arcgraph.de/sr/ -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
