Bug 1212058

We are rebasing systemd in 7.2 and we have the same problem as in fedora.


+++ This bug was initially created as a clone of Bug #1065572 +++

Description of problem:
libseccomp requires the kernel package. This means that any package containing a program linked to libseccomp will force the installation of the kernel package. One such package is systemd (in versions >= 209), which is often installed in containers and lighweight VMs which do not have a kernel. Installing the kernel (and dependent packages) is a very large overhead for the minimal installation.

I understand the reason for this dependency, but it doesn't really work: on one hand, seccomp does detect missing kernel capabilities, and on the other, even with the kernel package installed one can run an older kernel, since it is multi-installable.

Version-Release number of selected component (if applicable):
libseccomp-2.1.0-1.fc20.x86_64

How reproducible:
100%

Resolved in libseccomp-2.1.1-1.fc21.

This BZ is against Rawhide, do you see a need for this in F20 as well, or are you happy to see it in F21?

F21 is enough, thanks.

Okay, once I see the updated package propagate out to my Rawhide system I'll consider this closed.

This should also be fixed in all the GA releases ( F19/F20 ). 

People are running containers there as well

Yeah, but we have no intention of linking to libseccomp there.
