Cannot create hard link

/bin/ls: creating hard link `t2' => `t1': General system error

That's no surprise as BFS cannot support hard links due to its on disk representation.

Can this be fixed in BeOS? If not, we should at least modify our ln to report the "unsupported operation".

Huh? As I wrote, BFS cannot support hard links with its current on-disk representation. The only way to fix it is to make it incompatible, but even that would be a bit problematic with queries (the correct thing would probably be to show all hard links then, not just one, ie. the node must know all of its parents).

In any case, I changed the return code in hrev27501.

I agree that it should show all hard links as the user for example, could look for a certain file in order to delete it, and only later he would find out that he actually didn't do what it wanted to. At least that's a possible scenario.

In any case, I changed the return code in hrev27501.

Thanks, that's what I meant when I said (wrongly) to modify ln.

Isn't this a dup of #1036 ?

[axeld]

#1036 is not a duplicate; BFS is just one file system, others may implement hard link support -- the rest of the system should support it. In any case, this ticket can be closed.
