Hello;
  I don't know if this is a bug or a feature. While I was
playing around with 2.4.0 I (mistakenly) mounted an ext2
partition twice.

The excerpt from mount looks like this.
/dev/hda1 on /a1 type ext2 (rw)
/dev/hda1 on /mnt type ext2 (rw)

Under 2.2.13 I get

mount: /dev/hda1 already mounted or /mnt busy
mount: according to mtab, /dev/hda1 is mounted on /a1

Is this a bug or a feature?

System is an ABIT VP6, dual PIII 733Mhz, 1gb RAM,
30g ATA 100 drive, IBM Deskstar. DMA is on.
