[R-sig-Fedora] Problem with R, staged installation for packages, and samba share

[Iñaki Ucar]

Unfortunately, I cannot reproduce the issue here. :( I mounted a smb
share, created a symlink from ~/R, and installed dplyr without any
issue (apart from the installation process taking ages). Fortunately,
this rules out our binary R package as responsible for the issue you
are experiencing, unless I'm missing something.

Issue aside, may I ask what is the purpose of putting the library in a
smb share? May I suggest [1]?

I'm hoping maybe something will jump out as to how it configures on your setup. We aren't modifying R's source code at all, nor are we configuring it in a way that would affect this as far as I know.
