[Rd] running R with users home dirs on a shared filesystems

[Simon Urbanek]

User home is not used by R directly, so it is really up to whatever package/code may be using user home. In our setup we have all machines using NFS mounted homes for years. From experience the only thing to watch for are packages that use their own cache directories in $HOME instead of tempdir() - it is technically against CRAN policies but we have seen it in the wild.

Cheers,
Simon
