Diagnosing the persistent "Nothing to do" on v0.1.10 surfaced that removing %attr(,,name) from %files wasn't enough. systemd-rpm-macros ships its own rpm dep generator (/usr/lib/rpm/systemd.req) that parses User=/Group= directives from every .service file the package ships and emits Requires: user(NAME)/group(NAME) accordingly. Rpmbuild log from v0.1.10 shows these Requires are still emitted even after the %attr removal. Meanwhile the sysusers provides-generator emits group(NAME) in both unversioned and versioned forms, but only a versioned user(NAME) = <base64> when the u-line has GECOS/home/shell fields. The asymmetry leaves Requires: user(NAME) unresolvable. Add explicit Provides: user(NAME) back to both specs, with a comment documenting the actual cause (systemd unit parsing, not file attrs) so the next person touching these specs doesn't repeat the mistake. Why monsoon didn't hit this: it creates its user in %pre via groupadd/useradd (not sysusers.d), so no Provides are generated at all — matching the Requires: user(monsoon) by luck of the rpm solver treating unknown symbols as soft-fails for that path. Ours went through the sysusers Provides code path and hit the asymmetry instead. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

%description
|
|
Neuron is a per-node daemon for cortex inference clusters. It discovers
|
|
local GPU hardware via nvidia-smi, manages inference harnesses (mistral.rs,
|
|
llama.cpp), and exposes an HTTP API for model lifecycle management.
