Package: src:util-linux Version: 2.34-0.1 libblkid may incorrectly detect a bcache backing device holding a regular xfs filesystem as having both the superblocks for bcache and an xfs external log.
This may cause udev / blkid not to generate UUID variables/properties, and break references/symlinks by UUID, due to the ambivalent detection. The upstream fix [1] is present in v2.35-rc2, so it should automatically make its way into Debian sid in some time. It also describes the problem in more detail, and includes test-cases. cheers, [1] https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/commit/?id=d756af7d640c51ce8d1414607bd3f17eeecf2424 -- Mauricio Faria de Oliveira
