As wpeckham mentioned: a fine tuned SUDO is an asse t a system opposed to a 'free range" SUDO
Ok, so would it be correct to call partitioning disks as "dividing the disk" so that you can keep differing things separate? Easier for the computer to organize and find things.
It is correct to cal it that. In fact, it is part of the security...
Consider a scenario with everything in one lump...you (in your folder) keep downloading LEGAL MP3 music :P ad it grows, in the mean time, you keep installing that yummy free stuff...something will give...ad the OS will choke.
Now, in a partitioned disk, your OS is in a partition that cannot be influenced by user data. So, keep on filling up with stuff, the only limit you'll face is your folder, the OS will keep enough space...
Repo as in repository? The Debian repository is therefore found at www.Debian.org it seems as.
Nope...the OS has several setings where the locations are available, nothing to worry about, it's set fine...
Actually I am only using the root account to install software. Can this be an issue somehow? I don't really see the point in using my normal account since I have admin privileges on my root account (I probably have missed something crucial here :P).
Umm, yes you have missed something. The ROOT account is ONLY there to add/remove/update software, update the OS, do some maintenance, otherwise, you do NOT do day to day stuff (surfing, reading mail, listening to music and such) in that account. What happens is this: as soon as you become Root, you effectively are in a different folder...and a different partition.
Wanna try that? Okay. Install Midnight commander:
(provide root pass here)
apt-get install mc
now, once in root, start it up and look at the reported disk size
now issue an exit, you'll end up in your password, now fire up mc, and check the disk size...
no bug, different partition.
Once in root, ou are on the partition of the OS...mess that up and bamm, locate the DVD and re-install
A lot to take in, but, in a few weeks, this is your biotope
