When updating packages, it sometimes happens that the package distributor ships an updated version of some configuration files. Usually, the following dialogue appears:
==> Modified (by you or by a script) since installation. ==> Package distributor has shipped an updated version. What would you like to do about it ? Your options are: Y or I : install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation The default action is to keep your current version. *** bash.bashrc (Y/I/N/O/D/Z) [default=N] ?
I chose to start a shell to "examine the situation" (Z).
I probably have to add that the updated configuration file required root permissions to read & write.
I was a little surprised when I saw that the sub-shell was a root shell and I didn't have to provide a password.
Why do I get a root shell without having to type in the root password?
Isn't that a security issue?
