I also don't mind adding a in-memory 'volume-is-critical' property to UBI directly. I'm just a little hesitated to change the UAPI or the on-disk data structures for this features. > If you prefer going down that road instead I will work on patches for > git.infradead.org/mtd-utils.git instead. Yes. When done in userspace, it's also much easier to offer the --i-know-what-im-doing flag to still remove a critical volume. No need to touch UAPI. Zhihao Cheng, what do you think about this approach? Thanks, //richard
