Struct DefinitionDrift 

pub struct DefinitionDrift {
    pub path: PathBuf,
    pub installed_by_version: String,
    pub rendered: String,
    pub start_mode: StartMode,
    pub manager: DefinitionKind,
    pub writable: Vec<PathBuf>,
}

An installed service definition that differs from what this build renders for the same recorded installation.

Why this exists

An upgrade replaces the binary a registration runs and nothing else. A systemd unit written by 0.4.7 still carried LoadCredential=, which hands the daemon a copy of the credential frozen at service start, and lacked write access to the credential store. Every release after the fix kept running under that unit: the daemon could neither renew the token nor see one renewed by anybody else, and stopped starting runners the moment the frozen access token expired.

Fields

path: PathBuf

The definition file on disk.

installed_by_version: String

The build that wrote it, as its install record says.

rendered: String

What this build renders in its place.

start_mode: StartMode

The start mode it was installed for.

manager: DefinitionKind

Which manager reads the definition.

writable: Vec<PathBuf>

The directories the rendered definition lets the service write. A systemd unit fails before its first instruction (226/NAMESPACE) when one it lists is missing, or is under a home tree its ProtectHome=tmpfs hides without a BindPaths= for it. So whoever writes rendered creates them first: a host an older build installed may never have made one.

Implementations

impl DefinitionDrift

pub fn create_writable(&self) -> Result<()>

Creates every missing directory in Self::writable: the directory itself 0700, its parents (~/.local and its like, not this program’s to tighten) as the umask says.

Errors

The first directory that could not be created.
