Dear Answer Guy,
Nice column. I'm up to my eyeballs in updates (I'm updating 2 Linux machines and 1 Solaris). Anyway, in the current "The Answer Guy", you have a reply from Ted T'so on Maximal Mount Counts which suggests a solution to a problem I ran into last night. I'm updating a PC which has 2 SCSI controllers from S.u.S.E. to Debian, and found that because the controllers are seen in the reverse order now, that the devices the disks are assigned to has changed. Since the one controller is to be used for low performance or not always connected devices, I don't want that controller being seen first, which is what has happened under Debian. These labels, as in
LABEL=temp /tmp ext2 defaults 1 2
UUID=3a30d6b4-08a5-11d3-91c3-e1fc5550af17 /usr ext2 defaults 1 2
Are they assigned to the entire disk, or to partitions of a disk? The way the reply is worded it seems the label goes with the disk, and not with the partition.
Thanks for any light you can shed on this.
The UUIDs and labels are on filesystems (partitions), and not on disks (physical volumes).
Obviously things will get more confusing and interesting as we develop LVM (logical volume management) subsystems under Linux.
