Do not work with singularity 3.0.3+ds on Debian/Testing

[Trophime]

Hi,
can you confirm that motd is not working with singularity 3.0.3?
I've tried basic greeting example.

Checking now! I just shelled into a 3.1 container to verify that /.singularity.d/actions/shell is there (it is) so I'll try to reproduce your error right now, give me a few minutes!

This looks like a bug - it's written when we build, and then it seems to be overwritten again. I'll open an issue and link here.

This is a bug with Singularity, I've opened an issue, and it's up to the maintainers to address, sorry for the crappy discovery! https://github.com/sylabs/singularity/issues/3590

No problem ;)

Hi,
this morning I've tried to create the singularity image with your docker image -namely, I use the 2.4 image -(BTW an example on how to create an image with the singularity docker will be great for dummy like me).

Running the image with singularity 3, no motd appears
But it works fine with singularity 2.4.2...

@Trophime if you look in the Sylabs thread, this is happening because at runtime, they are generating those files on the fly. It doesn't matter what is built there, whether it be with Singularity or Docker - it gets replaced by that. I'm fighting for this on the thread, and if you feel that it's important (I think it's important) you should pipe in there as well. If we don't argue our case, it won't be fixed.
