Build several standalone tools into one binary and switch the function by name (symlink or hardlink). * btrfs * mkfs.btrfs * btrfs-image * btrfs-convert * btrfstune The static target is also supported. The name of resulting boxed binaries is btrfs.box and btrfs.box.static . All the binaries can be built at the same time without prior configuration. text data bss dec hex filename 822454 27000 19724 869178 d433a btrfs 927314 28816 20812 976942 ee82e btrfs.box 2067745 58004 44736 2170485 211e75 btrfs.static 2627198 61724 83800 2772722 2a4ef2 btrfs.box.static File sizes: 857496 btrfs 968536 btrfs.box 2141400 btrfs.static 2704472 btrfs.box.static Standalone utilities: 512504 btrfs-convert 495960 btrfs-image 471224 btrfstune 491864 mkfs.btrfs 1747720 btrfs-convert.static 1411416 btrfs-image.static 1304256 btrfstune.static 1361696 mkfs.btrfs.static So the shared 900K binary saves ~2M, or ~5.7M for static build.
