[tex-live] inclusion of texlive-includernw

[Roger Bivand]

The inclusion in current texlive of texlive-includernw (depending in 
packaged systems on R-knitr, not a texlive component), and its listing in 
texlive-collection-mathscience, hence in texlive-scheme-medium, is causing 
havoc for those who upgrade texlive because texlive-includernw tries to 
install R and many R packages without checking whether they are installed 
elsewhere. I can't see a list of maintainers of 
texlive-collection-mathscience, so cannot see how to get 
texlive-includernw de-listed urgently. It should be free-standing only, 
and should be re-written to check for dependency availability on R at the 
level of the user rather than root at install time. This probably cannot 
be done. The package should actually do the checking at run time only, 
providing helpful messages only.

The problem may be an over-ambitious Texlive Fedora packager - the issue 
hit me on upgrading from Fedora 28 to Fedora 29 today.
