Move the rule to run a bit later, after
the standard udev rules have called blkid.
Don't run blkid manually, and run probe-bcache
as a fallback which can be patched out in a
package that depends on util-linux 2.24+.
probe-bcache: bail if libblkid finds anything
Preserve our last-resort safety check here
in case earlier rules fail to call blkid.
Fail if the device has any leftover superblock or partition table label.
Add a --wipe-bcache flag to overwrite bcache superblocks and recommend
wipefs for non-bcache superblocks.
Once the device is safe to write, always zero immediately before the
bcache superblock.
Make sure errors go to stderr. Use pkg-config.
This means bcache devices will be registered earlier and in all
cases, not just when the rootfs fails to mount.
The initramfs hook is still there to ensure the bcache module
and udev rules are shipped if an initramfs is used.
Hi Kent,
please find a little patch (attached) to introduce probe-bcache.8 man page to
bcache-tools.
Thank you.
Cheers,
Dmitry.
