This shows a preliminary idea on how the SUMA requirements could be addressed reusing a lot of code from the current partitioning proposal and from the current Guided Setup.

In the control file, we just need to add a new attribute to identify volumes that must be allocated in its own separate LVM VG. The rest of the <partitioning> section of control.xml would stay as it is now.

And then, the new wizard would reuse many of the steps already present in the current Guided Setup.

Improving the "select disks" screen

See the "Improve devices selection in the Guided Setup PBI.

We basically have to answer three questions.

  1. Which information to display for each device?
  2. Which widget to use for a reasonable number of disks?
  3. Which widget to use for an insane number of disk?

Leaving aside what is correct and what is not, I have problems putting these two sentences from the chat together (from a purelly technical low-level POV).

  1. We can do any change in the WhateverImpl classes without affecting ABI compatibility "because users of library does not use Impl".

  2. A change in the public Bcache breaks ABI compatibility "for all programs linked to libstorage-ng, no matter if bcache stuff is used at all".

Why changing the Bcache class has an binary influence in the other public classes but changing WhateverImpl does not? How are they different in that regard? As I understand, the fact that WhateverImpl is non-public is a convention, not something the compiler knows.

Change 1

Instead of including the skelcd-* packages directly in the inst-sys, the inst-sys will contain a repo containing the skelcd-* packages and maybe also the licenses or any other stuff that the first steps of the installer (i.e. registration and any previous step) expect to get from libzypp.

Let's say that repo is located at /usr/share/fallback-repo

Change 2

needed partitions in a S/390 system

  • trying to install in a (E)CKD DASD disk
    • if the disk is formatted as LDL
      • raises an error (no proposal possible in such disk). FIXME: why?
    • if the disk is formatted as CDL
      • with a partitions-based proposal
        • if /boot is within a XFS or ext2/3/4 partition
          • requires no additional partition since the firmware can find the kernel
        • if /boot is within other type of file system

needed partitions in a PPC64 system SUGGESTED IMPLEMENTATION

That's what we should probably implement based on the conversation in https://bugzilla.suse.com/show_bug.cgi?id=1076851 Of course, we could change it again in the future if more requirements are found/proved.

  • in a non-PowerNV system (KVM/LPAR)
    • with a partitions-based proposal
      • if there are no PReP partitions in the target disk
        • requires only a PReP partition (to allocate Grub)
      • if there is already a PReP partition in the disk
You can’t perform that action at this time.
