bash login shell vs bash interactive shell

[Guest]

In debian systems (and in man bash), the login shell (got with su -) does not read /etc/bash.bashrc. Only the interactive shell does.
In Kubuntu, I enter "su -" to access root, and lo... the /etc/bash.bashrc gets read by the resulting login shell, and so I had placed all my bash initialiation customizations (i.e. PS1 and aliases) into /etc/bash.bashrc, so that all users including root will give me the same experience. Kubuntu does many funny things such as giving root privs to ordinary user passwords, hmmmm....
My question is: What has Kubuntu done that causes login shells to read /etc/bash.bashrc?

user$> cat /etc/profile
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).

if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then
. $i
fi
done
unset i
fi

if [ "$PS1" ]; then
if [ "$BASH" ]; then
PS1='\u@\h:\w\$ '

if [ -f /etc/bash.bashrc ]; then
. /etc/bash.bashrc
fi

else
if [ "`id -u`" -eq 0 ]; then
PS1='# '
else
PS1='$ '
fi
fi
fi

maybe?

ubuntu systems are set up for use with sudo.
so, in principles, the root account is locked and you should use sudo -i.
i also usually unlock the root account, though.

...Kubuntu does many funny things such as giving root privs to ordinary user passwords, hmmmm....

that is given by default (via sudo) to the user created at installation time.
i don't recall if this is also default for users added via system settings and stuff.
i should have thought it is not.
anyway...easily controlled.
remove the users in question from group admin.
or change the default settings in /etc/sudoers to give sudo access to your account only.

maybe... yes!
Thank you, that was the answer to my question. I went to my Debian machine and fixed it to work like the Kubuntu (in that respect).

I forgot to mention... Earlier I had actually made a root user in Kubuntu, and with its own password, which I use when I su -.
I know I didn't have to do that (and the Kubuntu wisdom says "don't!"), but I want to feel good in my familiar environment.
