failed to enumerate current paths: %w

Error message

failed to enumerate current paths: %w

What it means

After env preparation, startMonitor enumerates the current paths to monitor via artifactor.GetCurrentPaths(mountPoint, excludes). Any failure (walk errors, stat failures) is wrapped with this message and aborts monitor startup.

Solutions

1. Check the wrapped error to see which path failed
2. Ensure the sensor process has read permission across the mountPoint
3. Add problematic paths to cmd.Excludes so they are skipped during enumeration

// ensure sensor user can read everything under mountPoint
err := filepath.Walk(mountPoint, func(p string, fi os.FileInfo, err error) error {
	if err != nil { log.Printf("unreadable: %s: %v", p, err) }
	return nil
})

if err != nil && strings.Contains(err.Error(), "failed to enumerate current paths") {
	// retry with broader excludes or elevated permissions
}

When it happens

Trigger: GetCurrentPaths returns an error because filesystem walking fails — permission denied on directories, stat type assertion errors, I/O errors on the monitored mount point.

Common situations: Monitoring a mount point with unreadable subdirectories, excludes list referencing invalid paths, FUSE/overlay filesystem quirks.
