I need some Debian packaging help :) For http://tracker.ceph.com/issues/10587 I'm working to split out the "ceph-mon" and "ceph-osd" servers from the main "ceph" package. The goal is to allow someone to "apt-get install" only a monitor or an OSD without having to install the binaries for both. (ceph-mds is already split out in this fashion.) Here's what I'd like the process to look like for users: 1) User installs a Hammer MON/OSD with "apt-get install ceph". 2) User adjusts the sources.list to point to a newer Ceph version with the server split. 3) User runs "apt-get update" 4) Apt installs all three packages onto the user's system: "ceph", "ceph-mon", and "ceph-osd". 5) User then has the freedom to uninstall "ceph-mon" or "ceph-osd" as appropriate. I've gotten about 90% of the way there with the Debian changes, but I can't make "apt-get upgrade" do what I want in step 4. The only way I can make Apt pull in all three (ceph/ceph-mon/ceph-osd) during an "upgrade" operation is to make the "ceph" package depend on the -mon and -osd sub-packages. That option means that step 5 above doesn't work. 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"). But I'm not sure how to do that with Debian. Should I use a ceph-compat package? Something else? My WIP branch in GitHub is https://github.com/ceph/ceph/tree/wip-10587-split-servers . Any tips appreciated! - Ken -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
