now i use a initrd to boot my system, then switch to the real root filesystem, and i want to reuse the initrd. i see in the redhat, it use the blockdev --flushbufs /dev/ram0 to flush the initrd ram. and i can't find blockdev in busybox, so i use the freeramdisk /dev/ram0, but it seems has no effect.is there any other command to finish this job? thanks for any hints Best regards zhuzhenhua
