With respect to the hardlinks, here is an explanation cut from a mail from
Paul Sladen (on the list), which I hope he doesnt mind me publishing it...
Inodes contain data. `Files' (like
`/etc/passwd' are pointers to an Inode number (and therefore the write piece
of data).
A Hardlink is where you create a second pointer to the same numbered Inode
(there is also a reference count on the Inode data). So the reference
counts go to `2' for that data. If I create another hardlink the refernce
goes to `3' and there are now three seperate pointers to the same
Inode/data.
If you delete one of those files, all you are actually doing is removing a
pointer (such as `/etc/passwd') and decrementing the reference count back
down to `2'. So now when you create the file again (say `/etc/passwd') this
will now point at a new inode and a new block of data.
Whereas, if you *overwrite* the contents of any of those pointers you are
modifying the actual data in the Inode--and therefore the data that all the
other pointers see.
