Too much trouble to fix something that's probably never going to be merged anyway, closing.

I don't see any more SonarCloud errors that seem to be related to the changes in this PR.

@scimerman It looks like you may have accidentally have been running on a machine with `/etc/subuid` and unprivileged user namespaces enabled, because I don't see the messages you had before...

I compiled an apptainer with my suggested patch [above](#issuecomment-1279213080), and it printed ``` INFO: NOT running with [/.singularity.d/libs/fakeroot -f /.singularity.d/libs/faked -l /.singularity.d/libs/libfakeroot.so] ``` If I run the command by hand...

@ikaneshiro This is waiting on you.

I had the exact same problem going through the example. I got it to work by these commands as root ``` # echo /usr/local/lib/dmtcp >/etc/ld.so.conf.d/dmtcp.conf # ldconfig ```

Alternatively if you don't have root access you could set `LD_LIBRARY_PATH=/usr/local/lib/dmtcp` and then use the [workaround](https://github.com/apptainer/singularity/issues/5759#issuecomment-919523970) I posted for another issue.

Fixed by apptainer/apptainer-userdocs#143

This will probably be easier with the go-containerregistry in #1866.
