Yes, I saw your recent thread on the subject, and the others going back years, and it did motivate me to think more about this. I haven't seen an opinion from the current maintainers but I read that Neil Brown thought it should not be removed but instead the bugs should be found and fixed. So there doesn't seem to be any prospect of this feature being removed. Given that, and that there is a config option to disable it, I was hoping it would be deemed less controversial to also have a way to remove on next (incremental) assembly. If you can't have your first choice of having the feature removed, would you support that? As an aside, I'm having a devil of a game trying to get the Debian installer to let me use "CREATE bbl=no". Not only does debian-installer use a config file at /tmp/mdadm.conf, but it appears to constantly rewrite it every time you enter the MD configuration section, so realistically it seems that the only way to create arrays without a bbl is to do it manually from the d-i shell. https://lists.debian.org/debian-boot/2020/09/msg00074.html Cheers, Andy
