Comment 16 for bug 2058511

Sidenote for autoinstall, all partitions not known to curtin within the yaml will get dropped, so make sure to add dummy partitions with 'preserve: true' for each existing partition and their size (e.g. windows dual boot partitions). Ask me how i know 😉 Good thing i'm testing out in a VM.

Example attached one partition not to be used for the installation is 26.5G. While 100G within the yaml works, for 26.5G i needed to specify the proper bytes or the installer will crash and complain about a size mismatch.
