Original GitHub issue: https://github.com/netblue30/firejail/issues/2375

Use case:

firejail --env="LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libcurl.so.4:$HOME/.local/share/spotify/spotifywm.so" spotify
...
ERROR: ld.so: object '/home/damluk/.local/share/spotify/spotifywm.so' from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored.

This has worked with 0.9.56. If I can trust git bisect, the first bad commit was a7164cb3

Can you try using this?

firejail --ignore='noexec ${HOME}' --env="LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libcurl.so.4:$HOME/.local/share/spotify/spotifywm.so" /usr/bin/spotify

The ignore option helped, thanks!

as the commit you linked: noexec before 0.9.58 didn't recursively apply to paths, allowing programs in ~ for example to run when they shouldn't of

I suspect we will see more issues like this popping up over the next few weeks.
