You shouldn't do that there's the slightest possibility that you end up in an
untrusted path (where somebody can drop executable files) with cd and execute
something there (think of ls).
That's why . isn't in the PATH by default and normally shouldn't be.
It's actually not so problematic for non-privileged users, specially if
you tack the dot at the END of your PATH; system executables for e.g.,
'ls' will be found before the maliciously placed file in /tmp

NFS performance
Hi Guys, Reading the thread To kick or to clone ... that is the question gives the impression that NFS performance on z should be blazing fast if the guests are connected via either hipersocket or vswitch. My reality here is that I have a hard to to exceed a throughput of 1MB/s; I have no access to zVM. What kind of speeds should I be able to expect, what do I need to tell our z guys to change in zVM to get more ooomph? In a worst case scenario (guests on different IFLs, separate LPARs) I see as little as 120K/s, which is -what?- the speed of a 10MBit hub?

That would depend on a whole lot of things .. that does sound slow but could depend on anything from an overtaxed NFS server to network traffic going outside the box and back in (it happens) to limited CPU being available I'm a bit puzzled by the whole thing, as the behaviour seems to be diametrically opposed to things I've seen on Linux/Intel. We ran some tests, comparing NFS to scp between the same two instances, and scp beats NFS hands down, which I can't understand, really, by about a factor of 15.
