A long time ago, there was a thread regarding UID/GID registration (see http://lists.opensuse.org/opensuse-buildservice/2009-05/msg00221.html). AFAICT the question "how can one register a static UID/GID in the 0-99 range" wasn't answered.
There is no defined process to register uids there and I don't think we should start doing that again.
Context: the ceph project wants to reserve a UID/GID - being a distributed storage cluster, it's best if the UID/GIDs remain static across the whole cluster, and the most straightforward way to do this is to hardcode a UID/GID in a useradd/groupadd invocation in the rpm %pre script.
As long as process credentials are not 64/128-bit UIDs similar to NTSIDs, services ought to cope with different numerical UIDs. NFS made the jump with idmapd, so I am sure ceph can come up with something too. Perhaps even reuse idmapd.
I agree. There are still some use cases where same uids are desirable nevertheless. For example to be able to reuse a file system with data on it on different installations. cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.de/ SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Jennifer Guild, Dilip Upmanyu, Graham Norton, HRB 21284 (AG Nürnberg) Maxfeldstraße 5; 90409 Nürnberg; Germany -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
