Whether or not the kernel requests the passphrase depends
on whether or not the BOOT flag (0x2) on the provider is set.
You can check with "geli dump" if the flag is already set,
and if it isn't, set it with "geli configure -b".
For details see geli(8).

The passphrase is requested by g_eli_taste() in sys/geom/eli/g_eli.c.
