Let's have a look at what occupies [these 21 GB in my /dev/sda3](gibibytes-and-tebibytes.html).

In Arch Linux, one may use pacman [directly](list-packages-by-size.html "directly") to get this information, but there are at least two more convenient ways which lead essentially to the same results:

	expac -H M '%m\t%n' | sort -h

or even shorter

	pacgraph -c | sort -h

The result of the latter on my system is:

	1198MB urbanterror
	920MB xonotic
	856MB nexuiz
	514MB sauerbraten
	496MB warsow
	486MB texlive-fontsextra
	399MB openarena
	362MB freecad
	280MB quake4
	214MB fpc

The extra fonts for TeX is the only package I really need from this top ten of storage hogs.

For more visually oriented users, pacgraph offers an interesting view:

	pacgraph  -b "#333333" -t "#FFFFFF" -d "#FFFFBB"

I looked closely and discovered mono. WTF do I need mono for?

	[cobra@blackvelvet ~]# whoneeds mono
	Packages that depend on [mono]
	  nant
	  sparkleshare

	[cobra@blackvelvet ~]# pactree -r -d 1 mono
	|--mono
	   |--dbus-sharp
	   |--gtk-sharp-2
	   |--nant
	   |--ndesk-dbus

Or graphically:

	pacgraph -b "#333333" -t "#ffffff" -d "#ffffbb" -i "#ff0000" "#00ff00" "#0000ff" mono

Ah, sparkleshare! By the way: did I actually install all optional dependencies for sparkleshare?

	[cobra@blackvelvet Documents]$ pacman -T $(expac -Q '%o' sparkleshare)
	python2-nautilus

Naturally not, as I don't use nautilus.

Sparkleshare is located on the AUR and needs to be compiled whenever a new version is released. That's not a problem for my future desktop, which will be distinguished by a _very_ potent CPU. 😄

For a netbook like my Mini, however, the compilation of larger programs takes time and drains the battery. Let's see how many packages on my current desktop are from the AUR:

	[cobra@blackvelvet Documents]$ pacman -Qqm | wc -l
	64

Too many, if I'd plan to install my system on a netbook! I'm thus still hesitating to install [Archbang](psychological-factors.html "Archbang") on my Mini...

And what about the rest, i.e., packages explicitly installed via the official repositories?

	[cobra@blackvelvet Documents]$ pacman -Qqe | grep -vx "$(pacman -Qqg base)" | grep -vx "$(pacman -Qqm)" | wc -l
	272

The lists with these 336 packages which I have installed in addition to the base system will be very useful for a painless installation of my new system sometime at the end of this year.
