| |
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.
