Well, some new recognitions ... |
| 2 |
|
| 3 |
It turns out that those /dev/disk subdirectories don't necessarily have |
| 4 |
all the disk devices represented: |
| 5 |
|
| 6 |
1. by-id/ |
| 7 |
2. by-partuuid/ |
| 8 |
3. by-path/ |
| 9 |
4. by-uuid/ |
| 10 |
|
| 11 |
On my computer, only by-id/ - the subdirectory that's not set up in time |
| 12 |
- has links to /dev/sda?. Furthermore, by-path/ has even fewer of my |
| 13 |
drives represented in it. I haven't a clue what's going on. Since my |
| 14 |
swap file is on /dev/sda1, there's no way I can put it into/etc/fstab |
| 15 |
because I can't ensure the underlying filesystem is mounted in time. |
| 16 |
|
| 17 |
Another enigma - although /etc/init.d/localmount says: |
| 18 |
|
| 19 |
description="Mounts disks and swap according to /etc/fstab." |
| 20 |
|
| 21 |
there's also /etc/init.d/swap, which calls swapon. |
| 22 |
|
| 23 |
TODO: does mount -a mount swaps? ... I suspect not - the /description/ |
| 24 |
is apparently bogus. |
