systemd/test/TEST-50-DISSECT/test.sh
Zbigniew Jędrzejewski-Szmek ae6c598791 tests/TEST-50: support the case when /etc/os-release is present
We have four legal cases:
1. /usr/lib/os-release exists and /etc/os-release is a symlink to it
2. both exist but /etc/os-release is not a symlink to /usr/lib/os-release
3. only /usr/lib/os-release exists
4. only /etc/os-release exists

The generic setup code in test-functions and create-busybox-image didn't handle
case 3.

The test-specific code in TEST-50 didn't handle 2 (because the general setup
code would only install /etc/os-release in the image and
grep -f /usr/lib/os-release would not work) and 4 (same reason) and would fail
in case 3 in generic setup.
