Hi Frank,

Because Debian uses by default the "su" command.
You can learn about it using "man su" in a terminal.

If you really want to use sudo, you can read at https://wiki.debian.org/sudo

Hope that helps,
Olivier

There is, or was at the very least, an installation choice of whether or
not to setup sudo.

It is not foreign to /normal/ Debian.

I usually use PCLinuxOS, a distro which has a great distaste for sudo. 
As the debian people note, su allows someone with a root password (and
nobody else) to make system modifications, etc., which might harm the 
operation of the system. Sudo basically allows anyone with a user password
to do the same thing, and that's dangerous. The proper use of sudo 
(there IS a proper use) is to assign _specific_ tasks to some specific user,
so that such user can do _only_ certain tasks, like downloading programs 
from the repos, but not other tasks, which are assigned only to those
who have root password permissions, and presumably know what they're doing.

No it doesn't.  Only users who have been granted sudo privileges can use
sudo and only for the commands permitted them.

In reality, how many PC s have more than 1 user.  

If I had users other than myself, I'd think hard about a ding them to sudoers

We have UNIX's multi-user design to thank for this.

And there are lots of good config options to make a multi-system
multi-user shared sudoers file worthwhile.

You can make groups of hosts, groups of users, and groups of
commands, and assign them different privileges.

I've never seen sudo installed by default in any Debian, and I begin
with expert minimal netinstalls of stable, and I've never seen it
offered as an option there. My first two actions on reboot are to
install sudo and mc.

    By default you are asked to provide a password for the “root”
    (administrator) account and information necessary to create one
    regular user account. If you do not specify a password for the
    “root” user this account will be disabled but the sudo package will
    be installed later to enable administrative tasks to be carried out
    on the new system.

When you carry out a net install (or any installation, in fact) if you
decline to provide a root password then sudo is automatically installed
and configured for you, with the first user you create able to become
root with sudo.

This is all explained in the installer at the root password stage-
there is no need to install sudo manually post-installation.

If you want sudo, just don't provide a root password in the
installation.

On the other hand, I use both su and sudo.  If I have a protracted 
session with several different tasks that I need to complete all 
requiring root access I su to the root user.  If on the other hand, I 
only need to perform a single command, or so, I use sudo.  Both have 
their uses, though as already noted, Debian generally does one or the 
other as a default.  I install with a root password, and then bring in 
the sudo package post-installation.

Sudo -i opens a session as root with environment as if you did su -  except your non-root admin user doesn't have to know the root password.

Hmm...I wasn't aware of that particular switch....don't need su anymore 
that way.  Next install may be su-less:-)

That is incorrect. Anytime sudo is used, a password is required.
sudo -i does open a root session, after the password is entered. Of
course, you can set it up to NOT require a password for any user, but
that is not by default.

Not incorrect. Yes, a password is (usually) required. The _root_
password is not required. That's a big difference.

I use sudo -s for a root session. I can't remember the difference
between that and sudo -i, but it works for me.

On the other hand, if I need to be some other user, like the postgres
user, I use "sudo su postgres". There are probably better ways to do
that, too, but again, it works.

  sudo -su postgres

or

  sudo -iu postgres

depending on your preferences. It's all in the manpage :)

These days I only use su for some (archaeological) installations I
stumble upon at work.

It is indeed - thanks :-) I try and remember such things, but it's
harder when the old way works fine as well :-)
