Yes, I really mean udeb ;-) because of this from d/rules: ZSTD := $(shell grep '^udeb: ' /var/lib/dpkg/info/libzstd*.shlibs) That build-time configuration was to enable libzstd support on Ubuntu at a time when Debian did not yet have a libzstd udeb (but when Ubuntu did). IIRC, without this udeb, btrfs-progs compiled with support for zstd was nonfunctional in DI. Cheers, Nicholas
