|
---|
| 27 | - changed "/mnt/cdrom" to MNT_CDROM
|
---|
| 28 |
|
---|
| 29 | 10/18
|
---|
| 30 | - don't say unknown compressor if no compressor at all

|
---|
| 38 |
|
---|
| 39 | 09/14
|
---|
| 40 | - compare_mode() --- a couple of strings were the wrong way round,

|
---|
| 42 |
|
---|
| 43 | 05/05
|
---|
| 44 | - exclude /dev/ * from list of changed files
