I'm sorry if I come over like that; I just re-checked my replies and
frankly I don't see where I was aggressive. I'm not a native speaker
though, and if I'm doing something wrongly, please tell me off-list,
I like to improve.
In any case, sorry if anybody feels offended, it was certainly not

Actually, I said that I didn't care about the resource forks *being
I understand that they're important to the OS in a few respects, and
I know what they're used for. It's just that I see my Mac as
"mobile-friendly Unix", so basically all *my* needs don't use

Thanks, that helped me *lots*;
not so much in itself, but it put me on the track to search about
Mac hardlink implementation.
Short version: It completely breaks POSIX semantics and generally sucks.
Read this if you really want to break your brain:
Taking the worse FS, and then emulating the better one badly on it,
is really embarrassing.
I haven't been looking in the general direction of Ubuntu that much

My Linux box is quite full of VMs right now.
I will do the next best thing, though, for now: Make the external
disk UFS (which Mac OS supports natively), and see if that's enough
to fix it. If it isn't, I'll just have to see how many virtual boxes
I can move to archive... :(
