Hello!
It hasn't become clear to me in the gumd and image creation discussions
whether .rpm postin/un scripts can still depend on useradd and userdel
to create users for system services (example: avahi daemon runs as user
"avahi") dynamically.

If so, what are the right runtime dependencies (if any) to ensure that
the commands are really available?

If not, then I guess we maintain a static configuration of such daemons
and never modify it during package install/uninstall? Again, avahi is a
good example, because that's what's currently done for the "avahi" user
(see
https://review.tizen.org/gerrit/#/admin/projects/platform/upstream/setup).


In a few days systemd will be updated to v216. It contains feature called sysusers, which is responsible for creating such users and groups. Package that needs some users/groups should just provide appropriate config file. More information can be found on man page: <http://www.freedesktop.org/software/systemd/man/sysusers.d.html>.

Is it possible to use this tool in Tizen? If yes, then we'll enable it after update.

cheers,
