I know, and am usually more careful than that with unstable...

Indeed, and (off topic) I wrote a function `ess-rutils-update-pkgs' in
ess-rutils, to make this easy from iESS mode.  However, wont't this
break the Debian packages placed in /usr/lib/R, when the 'lib.loc'
argument matches this (this would need normally need super user access)?
