There must be something that the jffs2 subsystem is doing every boot, since I
regularly get the "jffs2 not ready yet, using temporary tmpfs overlay" message
during S10boot when the rootfs_data partition is large (20MB+) - I was speculating
on garbage collection or scanning delays.
Though, this might be specific to our system (rather slow SPI-NOR flash, active
mtd_oops module, etc.). If in essence you are saying this should never happen
during regular boot, it helps a lot limiting the potential root causes.
