I guess bugs in sh could affect a run with pkg_rolling-replace and other updates using pkgsrc?
I suppose strange things can happen?
Am I advised to rebuild my system (i386 and amd64) using build.sh after "cvs up -dP -A"?
I will still have the dubious /bin/sh from just this past week.
Or should I rebuild twice, the second time being with the new /bin/sh, or is that overkill?
