Eeverything else works as expected, touch, mkdir, and installing R packages, etc..
bash-4.2$ touch .ssh/test
bash-4.2$ ls -alh .ssh/test
-rw-------. 1 mah60 mah60 0 Oct 16 10:37 .ssh/test
bash-4.2$ rm .ssh/test
bash-4.2$ ls -alh .ssh/test
ls: cannot access .ssh/test: No such file or directory
In fact, I can run ssh-keygen to create the ssh key in /tmp or anywhere outside of my NFS home where I have permissions to write. Obviously writing to /tmp wouldn't be a very secure thing to recommend for our users. Normally I'd chalk this up to permission quirks on our NFS space except for the fact that the same commands work when run outside of the RStudio environment.
