app-misc/pax-utils-1.1.6 (a dependency of portage) has the seccomp use flag enabled by default, but this pulls in sys-libs/libseccomp, which has no prefix keywords. I don't really know what seccomp does, so I don't know whether it makes sense on prefix. I have also not checked whether sys-libs/libseccomp compiles.
I've masked the USE-flag, thanks
@Fabian, this affects the bootstrap. We need to roll out a new snapshot.
@benda, did you test with latest to see if a bootstrap succeeds from a recent snapshot?
@Fabian bootstrapping fails for me; `emerge` says that `**` needs to be added to accept_keywords for sys-libs/libseccomp. Adding `-seccomp` to the useflags in make.conf seems to fix it.
I've bumped the snapshot, sorry for the wait.
