Ubuntu mixing the harddisks

For some time I have six harddisks mounted. The harddisks are sda thru sdf, mounted to disk-a thru disk-f.
Before mounting the disks I edited fstab in such a way that sda was mounted on disk-a, sdb on disk-b, etc. etc.
I used the UUID's for this.
But after a reboot I noticed that the harddisks were in a different order than I had originally mounted them.
So, sda is not always sda, and sdf is not always sdf.
I thought that computers were very exact.

No, hard drives are not always enumerated the same due to minuscule timing differences. Which is the whole reason you mount by UUID or LABEL.
