    SubjectExporting which partitions to md-configure
    I'm putting the final touches on kinit, which is the user-space 
    replacement (based on klibc) for the whole in-kernel root-mount complex.
    Pretty much the one thing remaining -- other than lots of testing --
    is to handle automatically mounted md devices. In order to do that,
    without adding userspace versions of all the paritition code (which may
    be a future change, but a pretty big one) it would be good if the
    partition flag to auto-configure RAID was available in userspace,
    presumably through sysfs.

    Any feeling how best to do that? My current thinking is to export a
    "flags" entry in addition to the current ones, presumably based on
    "struct parsed_partitions->parts[].flags" (fs/partitions/check.h), which
    seems to be what causes md_autodetect_dev() to be called.

    Note that this should be available even if md isn't compiled into the
    kernel, thus making it possible to load md as a module before running
    kinit, or to make the equivalent of the kernel mounting sequence from a
    totally runtime user tool.
