--- Begin Message ---Package: libeatmydata1 Version: 82-6 Severity: normal Dear Maintainer, Please consider installing /usr/lib/x86_64-linux-gnu/libeatmydata.so.1.1.2 with the setuid bit set. Without that, executing some commands (like fusermount) in eatmydata-enabled chroots give weird error messages like: $ fusermount -u sshfs_mountpoint ERROR: ld.so: object 'libeatmydata.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored. $ ..yet the command also succeeds. This is because (from ld.so(8)): LD_PRELOAD A list of additional, user-specified, ELF shared libraries to be loaded before all others. The items of the list can be separated by spaces or colons. This can be used to selectively over‐ ride functions in other shared libraries. The libraries are searched for using the rules given under DESCRIPTION. For set-user-ID/set-group-ID ELF binaries, preload pathnames containing slashes are ignored, and libraries in the standard search directories are loaded only if the set-user-ID permission bit is enabled on the library file. Thanks! -Nikolaus

Besides, random internet posts (so no idea how right they are), say that it wouldn't work anyway, as linux would refuse to load setuid libs for security reasons. Whatever linux and ld do, I'm not going to ship a setuid library, especially eatmydata. > $ fusermount -u sshfs_mountpoint > ERROR: ld.so: object 'libeatmydata.so' from LD_PRELOAD cannot be preloaded > (cannot open shared object file): ignored. > $ if you really need eatmydata to run fusermount (not sure of the gains), then you are by yourself, and you can just use dpkg-stateoverride.
