 ### Building an image
+> [!NOTE]
+>  If you are planning to spin custom images you will need to implement some type of mechanism for loading the `/usr/lib` account and group files, Arkane uses a patched [libnss-extrausers](https://github.com/arkanelinux/libnss-extrausers) PAM module to achieve this, Fedora Silverblue uses sssd
