That option means that step 5 above doesn't work. can we - have another package named "ceph-base" which packages whatever ceph currently has now. - make the "ceph" a meta package which only offers the dependencies to ceph-mon, ceph-osd, ceph-mds? and let ceph-{mon,osd,mds} Depends on "ceph-base" instead? > > I must be missing something in ./debian/control to make this work. > > For the RPMs, I was able to make this work by introducing a > "ceph-compat" metapackage that used RPM's "Obsoletes" to replace the old > "ceph" and require "ceph-mon" and "ceph-osd" (which in turn required the > new "ceph").
