When the system is installed in an extended partition, the fast reboot does not work:

# grep findroot /rpool/boot/grub/menu.lst | head -1
findroot (pool_rpool,4,a)
# dtrace -wq -n 'pid$target:a.out:parse_fastboot_args:return {exit(0)} ' -c "reboot -f" 
reboot: Failed to process GRUB menu entry for fast reboot.
    Invalid format for findroot
reboot: Falling back to regular reboot.

#

There are two problems in libgrubmgmt:

First, the findroot() is failing here:

397        ++pos;
398        if (!IS_PRTNUM_VALID(barg->gb_prtnum = pos[0] - '0'))
399            return (EG_FINDROOTFMT);

Second, the get_sol_prtnum() is failing, because it is processing only primary partitions:

105    for (i = 0; i < FD_NUMPART; ++i) {
106        if (ipart[i].systid == SUNIXOS || ipart[i].systid == SUNIXOS2)
107            return (i);
108    }
109    return (PRTNUM_INVALID);
