What about /var/log? The various logfiles are written very frequently. |
| 16 |
Could you NFS mount this from somewhere else? I wouldn't rely on wear |
| 17 |
levelling in a CF card, only on an SSDdrive. |

I used one of their adaptors to run a MythTV frontend from CF, although |
| 24 |
it netboots now. I used a variation on a live CD setup, so the card was |
| 25 |
not written to. |

/media/sdb1 is the mount point, not the device node. Use |
| 41 |
|
| 42 |
dd if=/dev/sdb of=CF.img bs=4096 |
| 43 |
|
| 44 |
to read the card, switch of and if to write a new one. Of course, all the |
| 45 |
cards have to be the same size. |

You don't need to format at all if you dd the whole drive, as that |
| 52 |
includes the partition table, MBR and the kitchen sink. |
