R devel - Nov 2012 - Option to set permissions on directories and files after package installation

The R package on Debian (and hence Ubuntu) has had a default for close to a
decade to install into /usr/local/R/site-library/. This came from a
suggestion by Kurt and Fritz, and I still think of it as rather useful.

To me, this suggests multiuser mode, preferably without sudo.  One can get
close via group membership on the directory, but ultimate this always fails
because tools:::.install_packages() insists on putting 0644 / 0755 modes on
everything as seen from the following selection from that function:


                ## not clear if this is still necessary, but sh version did so
                if (!WINDOWS) Sys.chmod(file.path(dest, files), "755")


                if (file.exists(f)) {
                    file.copy(f, instdir, TRUE)
                    Sys.chmod(file.path(instdir, f), "644")
                }


		Sys.chmod(Sys.glob(file.path(instdir, "data", "*")),
"644")


	    Sys.chmod(Sys.glob(file.path(instdir, "demo", "*")),
"644")


                    Sys.chmod(Sys.glob(file.path(instdir, "exec",
"*")), "755")


                Sys.chmod(i2_files[execs], "755")


I would like to have the option of haveing the effect of setting umask 0002
so that people in my group can replace packages.   The simplest may be to
replace "644"/"755" with "664"/"775" is
a suitable option is set. More
involved schemes are of course possible too.

Naturally, I would be happy to work on patch if there was any indication that
the patch would be reviewed and possibly included.  

With that: comments, please. Is this seen as sensible or deemed nutty and
off-limits?

Thanks, Dirk

I second the request to allow specification of the permissions to use when
installing packages, preferably controllable via a site-wide configuration
file.

I use this all the time for similar reasons (but not on debian).  I
currently post-process with chmod and chown.  I support this request,
and I would be happy if the owner could be set as well.

Best,
Kasper
