Description
This testcase ensures it's possible to use package layering features of rpm-ostree.
Setup
- Ensure you have a booted rpm-ostree-based Fedora install (e.g. IoT, CoreOS, Silverblue or Kinoite)
How to test
- Install a package for a simple application with no dependencies which is not in the base image, e.g. 'htop'
# rpm-ostree install htop Checking out tree 7130f87... done ... Resolving dependencies... done Will download: 1 package (815.9?kB) Downloading from 'updates-testing'... done Importing packages... done Checking out packages... done Running pre scripts... done Running post scripts... done Running posttrans scripts... done Writing rpmdb... done Writing OSTree commit... done Staging deployment... done Added: htop-2.2.0-8.fc32.x86_64 Run "systemctl reboot" to start a reboot
- Reboot the system
- Verify that the 'htop' package is layered succesfully and usable

htop 2.2.0
- Install a server-type package which pulls in multiple dependencies, e.g. 'httpd'. If 'httpd' is in the base image, try 'postgresql-server'

- Reboot host
- Verify that 'htop' is still layered and 'httpd' (or 'postgresql-server') is also layered with dependencies (for 'postgresql-server', check that 'postgresql' is also installed)

/usr/bin/postgresql-setup --initdbthen start and test the 'postgresql' service, and runsu postgres -c "psql -l"to check that it works
