Hmm, in theory you shouldn't have access to your home dir under rsh
since it's a share from another machine which isn't available to a
process running under a SYSTEM environment. Except your home dir
is publically available (i. e., no authentication needed).
I don't understand what you're doing, probably. Do you rsh to the
same machine as you're doing the first `pwd' on? Or do you rsh to
the server which provides your home dir? Did you try e. g. an
rsh hostname echo foo > foo
to check if touch is performing unnecessary tests or an
rsh hostname strace touch foo
to look into the strace what happens?
