Hi all,
I have a Cent OS 5 box with a fairly full install which I'm trying to strip down. Since this machine will be running headless I would like to remove all of the X11 stuff which is installed on it. However, it seems that the "redhat-lsb" package, which I would like to keep, is dependent on X11
- redhat-lsb depends on /usr/bin/lpr - /usr/bin/lpr is provided by cups - cups depends on paps - paps depends on pango - pango depends on libX11
Is it possible to safely break this dependancy chain so that I keep redhat-lsb while removing X11? I'm trying to keep all of my package management restricted to 'yum' and I certainly want to avoid 'rpm -- nodeps'.
Looking at /etc/alternatives/ makes me think there must be another package besides cups which provides /usr/bin/lpr but I can't seem to find it. I won't be doing any printing from this machine so I would even be happy with a dummy /usr/bin/lpr which simply throws away anything it receives.
Thanks,
- Richard

libX11 is a library. You can remove the other X11 components but still keep the shared library. You won't have a functional X11 - just one library that is from X11.
This is not uncommon - many servers run php/python/perl etc. modules from drawing stuff that have dependencies on an X11 library - but do not have X11 installed, just a shared library from it.

You can't break the dependency w/o using nodeps. There is no technical reason to keep the lsb package if you are not going to keep the things it depends on. And if you don't keep the dependencies, then you don't have a fully lsb compliant system. There is no technical problem with that, though you may have internal to your company issues.
If you don't need them, yum erase away.
