Any ideas on getting init.d/swclock to work in Alpine diskless mode?

Persistent storage filesystems are defined in /etc/fstab for LBU, APK cache, and the swclock file defined in conf.d/swclock[swclock_file]. The required filesystem isn't mounted when swclock runs in boot/shutdown (screenshots below). Modifying init./swclock[depend()] with "need localmount" causes boot errors and 60s shutdown delays. Other localmount depend() options failed too.
