Is it distribution provided or did you build it yourself? The mount command has been implemented in Rust for a while (since 28f703cc256f "Rust now integrated into bcachefs binary") and if building without Rust support (BCACHEFS_NO_RUST defined), that command won't be included in the binary. In more recent versions of bcachefs-tools, building without Rust is not supported at all. I don't think this has anything to do with loop devices specifically. - Thomas Bertschinger -- Mailing list info: https://lists.linux.it/listinfo/ltp
