Change partition numbering

[Rodolfo Medina <rodolfo.medina@gmail.com>]

Hi all.

After resizing a partition on my hard disk, partition numbering changed and now
number 7 comes before and number 6 comes after:

Model: ATA SAMSUNG MP0402H (scsi)
Disk /dev/sda: 40.1GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags: 

Number  Start   End     Size    Type      File system     Flags
 1      32.3kB  8390MB  8390MB  primary   fat32           boot
 2      8390MB  40.1GB  31.7GB  extended                  lba
 5      8390MB  9434MB  1045MB  logical   linux-swap(v1)
 7      9434MB  26.2GB  16.8GB  logical   ext3
 6      26.2GB  40.1GB  13.8GB  logical   ext3

Is it possible, and how?, to correct that and change back 7 with 6?  Googling
around found no solution.

Thanks for any help,

Rodolfo
