Warning from Sys.junction when using network drive.
Unfortunately, junctions cannot link to a network drive, they only can link directories on the same computer (possibly on different local volumes). This is a limitation imposed by Windows. I have updated the documentation for Sys.junction in R-devel accordingly. Tomas

I am running 3.4.3 on a windows server and I ran the code in a new session. I get a warning when running packrat::init() on a project that is located on a windows network drive. The warning I get is Warning message: cannot set reparse point 'U:/packrat5/packrat/lib-R/base', reason 'Access is denied' The error is created based inside the function .Internal(mkjunction(fr, link)) which is called from Sys.junction(). I have run Sys.junction inside the RStudio debugger and I checked that the 'U:/packrat5/packrat/lib-R/base' could be accessed via the windows file explorer before the .Internal(mkjunction(fr, link)) call is made. Looking at the code for do_mkjunction(), the warning looks to be thrown based on the return status from DeviceIoControl. I setup a project on the C: drive and tried the same packrat::init() code. The call to .Internal(mkjunction(fr, link)) did not produce an error. I would appreciate any help you can provide on this issue. Thanks, Mark [[alternative HTML version deleted]]
