Why are KDE, Gnome, OpenOffice and QT installed to /opt ?

I just installed them with pacman -Sy kde, pacman -Sy openoffice-base etc. and they were all installed to /opt, instead of /usr. Firefox was installed to /opt too. (all of the other packages are installed to /usr.)
What do I need to do so that they will all be installed to /usr ?

Placing those programs in /opt is intentional and part of the way *Nix works.

Check Linux Forum: opt - Linux File System for background info.


Booting with apg Openrc, NOT systemd.
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

It's also described in the Arch Linux install documentation included on the CD, which even is available during install. It's used for bigger packages and groups, to keep it all in one place. Makes it a LOT easier to find what you're looking for.

You want them to be installed to /usr because of the PATH-variable? If so, just edit /etc/profile and then source /etc/profile to update it, and all binaries will be accessible.

Re: Why are KDE, Gnome, OpenOffice and QT installed to /opt ?

Matter of fact I want them in /usr because I made a partition just for /usr, so that all the packages will be installed to one partition.
When I was using Debian (and other distros also...), it installed everything to /usr, so I assumed it will be the same in Arch. As it is now, it fills up my / partition, which isn't really big.
Although this is quite a good (and sensible..) idea, I can't let it fill my / partition. Is there a way to assign both /usr and /opt to one partition ?

You can do

     pacman -r [alternative root directory]

but that's not advised (I'm not sure why tbh).

Personally I'd symlink a folder in /usr to /opt:

     mkdir /usr/myopt
     ln -s /opt /usr/myopt

In case you haven't used a soft link like this before, it's basically like a shortcut in Windows - if you put something into /opt now, it will actually be put into /usr/myopt .

Isn't it supposed to be
ln -s /usr/myopt /opt ?

because I tried to do, for a test,
ln -s /opt.test /usr/myopt
and then
touch /opt.test/foo
and it created foo on /usr/myopt.

I confuse alot with the target and destination in 'ln -s', but maybe this time I'm not wrong?

no that seems right, target comes first.

Always an easy way to find out, ask the manual page!
