systemd depends on different derivation of systemd #98094
Description
Describe the bug
Installing systemd pulls 2 different derivations of systemd
To Reproduce
Steps to reproduce the behavior:
1.
nix-env -iA systemd -f https://github.com/NixOS/nixpkgs/archive/release-20.09.tar.gz # or `master`
# ls -ld /nix/store/*systemd*

dr-xr-xr-x 7 root root 4096 Jan 1 1970 /nix/store/kmlzasz1lbkigpirk4vwyg14g206wq18-systemd-246
dr-xr-xr-x 7 root root 4096 Jan 1 1970 /nix/store/lkzflryr02ahapqln1cwrkkhncwfb91y-systemd-246
# du -sh /nix/store/lkzflryr02ahapqln1cwrkkhncwfb91y-systemd-246 /nix/store/kmlzasz1lbkigpirk4vwyg14g206wq18-systemd-246
27.5M /nix/store/lkzflryr02ahapqln1cwrkkhncwfb91y-systemd-246
27.7M /nix/store/kmlzasz1lbkigpirk4vwyg14g206wq18-systemd-246
# nix path-info -r /nix/store/kmlzasz1lbkigpirk4vwyg14g206wq18-systemd-246 | grep systemd
/nix/store/kmlzasz1lbkigpirk4vwyg14g206wq18-systemd-246

Investigating further, it seems that libsystemd-shared depends on cryptsetup, which depends on devmapper which depends on udev from another systemd store. it can be confirmed by going up the library chain with ldd and readelf -d

Additional context
Truth to be told, I'm running nixos in a podman container (podman run -it --rm nixos/nix:latest).
