Yep, I did fail to understand they don't have the same size --- I was
just watching the output of df:

root at miranda:/root# df | grep /tmp
tmpfs                     1827264       69   1788202   1% /tmp
/dev/mapper/MIRANDA-TMP   1827264       69   1788202   1% /tmp

but mount shows

root at miranda:/root# mount | grep /tmp
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime,size=734240k)
/dev/mapper/MIRANDA-TMP on /tmp type ext2 (rw,noatime,errors=continue)

Thus I suppose that, although a tmpfs is automatically mounted on /tmp
at first, later on the logical volume I specified in fstab is also
mounted, with df only able to show the size of the file system actually
being used (thus wrong in the tmpfs line).
