Can't create hard links on a shared folder (= can't use zsh if home directory is shared folder)

It seems the shared folders do not allow hard links to be created (link() system call). The result is always EPERM, Operation not permitted. A simple "touch foo; ln foo bar" on a shared folder will demonstrate the problem. This is with VirtualBox 2.2.4 on Mac OS X 10.4.11 host, Linux 64-bit client (tried both Ubuntu 8.04 LTS Server x86-64 and Scientific Linux 4.8 x86-64 (a RHEL4 variant)).

The way I actually noticed was that the zsh delivered with scientific linux (zsh 4.2.0) tries to create a history lock file with link() and fails - and goes into an infinite loop. There's no such problem with the ubuntu version though (zsh 4.3.4). This makes it rather more difficult to use zsh as a login shell :-) I'll see if I can coax it to not use that way of locking.

However, hard linking support would be nice.

#818 only fixed the soft link aspect, hard links still don't work.

It might probably make sense to remove the duplicate status on this one and clearly mark #818 as only fixing the soft link part, continuing with the hard link part here?
