I do know the USB stuff changes but I wasn't sure about the others. I |
| 59 |
would think the main drives in a system would come first but one could |
| 60 |
never make that promise. I'm giving serious thought to using the |
| 61 |
labels. It would also mean that I don't have to remember what partition |
| 62 |
is what. Currently I would mount and then list what is in the directory |
| 63 |
to see what is in it and figure out what it is. With the labels |
| 64 |
feature, even fdisk would tell me what is what. |
| 65 |
|
| 66 |
This would be a good time to move the OS to a new drive. If things work |
| 67 |
out, run from the new drive. If things blow up, boot the old drive with |
| 68 |
the old kernel, old fstab and other settings. |
