This was my expectation by using `-S /etc=etc` but I am not sure it works. Or I miss something. For example, I run: docker run -ti --rm --tmpfs /tmp 6d1dfcc93a87 bash --login or without --login. Then nothing "useful" is sourced. Moreover, `ls -al /etc/` returns: total 20 drwxr-xr-x 2 0 0 4096 May 20 13:01 . drwxr-xr-x 1 0 0 4096 May 20 13:01 .. -rw-r--r-- 1 0 0 13 May 20 13:01 hostname -rw-r--r-- 1 0 0 174 May 20 13:01 hosts lrwxrwxrwx 1 0 0 12 May 20 13:01 mtab -> /proc/mounts -rw-r--r-- 1 0 0 111 May 20 13:01 resolv.conf I mean the profile is still under for example `/gnu/store/n8sfl91mk8xrcrl325lc46ajihjssi8d-profile/etc/profile` and it is really annoying to find the hash. Maybe I miss something.

It sounds like it would greatly improve things. I am not sure it will fix the issue here. However, it should improve things for the issues described there: https://lists.gnu.org/archive/html/guix-devel/2019-05/msg00326.html (if I understand what a Docker mainifest file is) All the best, simon
