no. just no. |

The right thing, is not to mount by partition naming, but by uuid. That way it |
14 |
does not matter if the partition is called 'hda2' or 'sda2' or 'srX' or 'sgX' |
15 |
or whatever. Just mount by-uuid. It always works and it is great. Moved |
16 |
around a partition? created some before it? No problem, because you don't |
17 |
mount '/dev/hda2' you |
18 |
mount '/dev/disk/by-uuid/c1a84bd9-91f1-420e-9880-d4290599a399' |

and all that problems can be solved with mounting by uuid for the harddisks. |
