[aur-general] System cleaning?

[Andrei Thorp]

You can do

pacman -Qdt to list all packages that were installed as dependencies
but are no longer required. You can then take these packages and
remove them. You can do this automatically like:

pacman -Qdt | sed "s/ .*//" | sudo xargs pacman -Rs

This will delete all packages that are installed as a result of
unneeded dependencies. In the future, use pacman -Rs to not have to do
this (rather than pacman -R).

Also, consider switching to ext4 and doing a defrag when you're at it.
ext4+defrag has extends that cause shorter seek time.

Cheers,

-AT
