Subject: bug#28157: “r-minimal” retains no reference to “which”
Date: Sun, 20 Aug 2017 13:16:50 +0200

R provides a function “Sys.which”, which embeds the full path to “which”
at configure time.  The path it embeds is that of “which” *before*
grafts.

The final package does not retain any reference to the “which” package,
however.  What’s worse: this cannot be fixed by adding “which” to the
environment, as “Sys.which” holds a reference to the ungrafted “which”
package.

This is a problem in containers, where the ungrafted “which” will not be
available even when the “which” package is added to the container.

It may also be a security problem, because R references an ungrafted
package.
