Fixed using packages from the Full (offline) medium (bsc#1258828)

Problem

• When booting the Agama installer Full medium (the offline one) from harddisk or USB flash disk the packages from the medium are not used. Booting from DVD works fine.
• The relevant error message in the log;

[zypp::media] Attached: hd:/run/initramfs/live/install?device=/dev/disk/by-id/scsi-SATA_VBOX_HARDDISK_VB73e6bfd0-6aca5a67-part2 attached; localRoot "/run/initramfs/live/run/initramfs/live/install"
[zypp::media++] checkDesired(1): desired (report by zypp::media::NoVerifier)
[zypp-core] mediafacade.cc(provide):467 THROW (EXCPTR):    File './repodata/repomd.xml' not found on medium 'hd:/run/initramfs/live/install?device=/dev/disk/by-id/scsi-SATA_VBOX_HARDDISK_VB73e6bfd0-6aca5a67-part2'

• The installer then complains about missing packages and registration although the user booted the Full medium and the registration should not be required.

Solution

• The problem is that libzypp automatically adds the mount point prefix to the path if the device is already mounted, if Agama adds the prefix in the URL as well then it is used twice in the end. Agama should use just the /install path in the URL instead of /run/initramfs/live/install.

Testing

• Updated unit test
• Tested manually, the Full repository is correctly added and the packages are used for installation

Note: For DVDs it uses the correct path.

I would say there are some left-overs.
