[R-sig-Debian] Fw: Default shell in Debian 6 of R is SH instead of BASH

[Johannes Ranke]

Well, R is cross-platform. If you issue system commands I think it is clear 
that it may differ depending on the system (think if Windows or Mac).

Anyway, you would need to bring this up on debian-devel or the respective 
fedora lists, as it seems to me you are complaining about the system defaults. 
As far as I can see, this is not under the control of the R packaging. Please 
correct me if I am wrong.
