How to make /.singularity.d/libs/libfakeroot.so visible to fakeroot also visible to normal user?

[Heng-Zhou]

I installed package libfakeroot using command apt install -y libfakeroot in the definition file in hope that /.singularity.d/libs/libfakeroot.so could be seen by normal user. But because the user is (fake) root when the package libfakeroot is installed, this file is only visible when I shell into the container as a fake root user (shell --fakeroot). If I shell into the container as a normal user (without --fakeroot), the directory /.singularity.d/libs/ is empty. Is there any way to make /.singularity.d/libs/libfakeroot.so visible to fakeroot also visible to a normal user? Thank you.

Bit confused here - SingularityCE has no handling of libfakeroot. If you install it in the container then it won't be bound into /.singularity.d/libs as that's where SingularityCE puts GPU libs etc. that are bound in from the host.

Are you sure you aren't using Apptainer... but running it via the singularity alias it installs? Apptainer does use libfakeroot, but SingularityCE does not. What do you get from singularity --version?
