Today I want to create a terminal server based on vnc and guacamole on rackspace. For this I commissioned a SUSE 13.1 server. Now when I install KDE using yast I get a strange question:

WTF? The system is proposing me to "not forbid installation of libqt4-x11"? Who forbid that at all and why?

The answer is quickly found: libqt4-x11 is "tabooed" which is indicated by three dashes in yast:

 --- │libqt4-x11-32bit            │Qt 4 GUI related libraries          │4.8.5       │           │

I want to un-taboo all packages, I want to allow me to install them all. So I have to find where the system stores the tabooed packages. No problem, I start

strace -ffe open yast2

This will start yast2 and show me every file it opens. Then in yast2 I taboo MozillaFirefox-devel and look through the files being opened by yast2.

Seems there is an interesting directory /etc/zypp. Yast2's software module is based on this zypper thingy from SUSE. And indeed this seems to be it:

tweedleburg:/etc/zypp # cat locks

type: package
match_type: exact
case_sensitive: on
solvable_name: MozillaFirefox-devel

Now back to rackspace. In their system, /etc/zypp/locks has 3624 lines, versus 6 lines in my desktop computer after disabling MozillaFirefox-devel.
