I got my Linux start with Ubuntu and unfortunately, got in the habit of using sudo for everything and not having a root account. After upgrading to the latest sudo package, my user's $PATH variable no longer points to /usr/sbin and thus, I can't do package management involving ldconfig using sudo. I'm sure this is in line with Debian/POSIX policy, and I approve wholeheartedly. I know how to hack around this as well, but I'm not sure if it's a good idea.
So my questions is: Should I not use sudo and use su/root prompt more often?
What is the aptosid community's take on it? |

Just say "No" if an update wants to change your custom settings back to default.
And as BT is saying: we don't recommend it. At work (I am not the admin) we have a set of 20 computers running dualboot with Windows XP and Ubuntu, anyone using Ubuntu could trash the PC he/she is working on because of sudo and the lazy admin settings. Well ... it's not critical, it's just a school, and the computers are used for teaching ... but!
I talked to the admin, and he might change it if he finds time (schools don't pay for admin work here!), but he had to switch to Ubuntu because the kids wanted it (they just know Ubuntu). The admin himself is a Debian user.

hello seasons,
please have a look at our manual :
Thanks for the obligatory RTFM post, but I expected to find it under System Administration. Oh well..
Yeah, I guess I'll have to break the habit of sudo and use su more. I shouldn't insult my own intelligence... |

su --> login as root
sudo --> run as root
With su you're talking permissions, owners, groups
With sudo you're talking sudoers, list of people who can run things "without being root" or "having permissions on the files"

Thanks, I already knew that <stuff> though. I guess what I'm really wondering is why the /sbin got removed in the default config just now?

I thought I did, but it was before morning coffee, so...  |

Implying a rudeness stating "RTFM" is surely cool. But actually that means WTWFSFMPA: "write the whole fucking shit for me personally again".
No offence.

| Yeah, I apologize for implying rudeness when the poster actually answered the original question I posed. I guess if I really want the answer to my question, I'll have to dig through the changelog/bug reports. Thanks anyway. |

@seasons
The answer is, as I stated: during the update you were asked if you want to replace your configuration by the new package or not. The answer is N (no) or just hit enter (because that's default). If you type Y (yes), your configuration is gone.
I am quite convinced that you typed Y and hit enter.

Just for the record: For me /sbin and /usr/sbin were never in $PATH for a user -- as (suprise suprise) a user can't execute programs in it so its useless to make them available in tab-completion.
Further more as you said you can't do package management: apt-get and friends are not in /usr/sbin.
And last but not least: If you do tab-tab after sudo, it's not the bash doing it's usual tab-completion here but the specific bash-completion for sudo. So I would ensure first that the bash-completion is actually loaded…
(It would be a surprise if sudo in its completion doesn't include sbin's…) |

Actually, I confirmed that I did indeed keep the old configuration, which is what's causing the issue. The sudoers file now includes this line:
Code:
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

Ok, does this work for you?
Code:
sudo ldconfig
