I found this article:

 http://unix.stackexchange.com/questions/18752/change-the-number-of-the-partition-from-sda1-to-sda2/18759#18759

According to it, I did:

 # sfdisk -d /dev/sda > myfile

and edited sda.bkp my way.  Then,

 # sfdisk --no-reread -f /dev/sda < myfile

.  Then I edited /etc/fstab properly and rebooted.  But then I had to rescue
the system: from a Debian installation disk, in rescue mode, from the boot
partition, I did:

 # grub-install /dev/sda

, then rebooted and now it seems ok.  Maybe I had to give the last command
before rebooting the first time.
