If you are using R, and the system gets fully wiped every week, you might have to keep the @add_rcran* script.

Note that I suspect you might be able to copy the ~/R directory and propagate to the new system, so you wait less time for the packages to build (this assumes you have the same operating system from session to session).

So, you could try setting up a system, and then:

tar -zcf R.tgz R

on it, and save R.tgz somewhere (e.g., on a USB), and then after install R next time, copy R.tgz back to the new home directory, and unpack it with:

tar -xf R.tgz

If the afni_system_check.py looks good, then great; you can even run

rPkgsInstall -pkgs ALL

again at that point, and it would hopefully tell you everything is uptodate.
