[Bug 2141545] Re: [SRU] add swap file or partition to LicheeRV preinstalled image

[Heinrich Schuchardt]

Using livecd-rootfs/24.04.96 I locally built an image for the Nezha D1.
Cloud-init correctly creates the swap space:

ubuntu at ubuntu:~$ cat /etc/fstab 
LABEL=cloudimg-rootfs   /        ext4   discard,commit=30,errors=remount-ro     0 1
LABEL=UEFI      /boot/efi       vfat    umask=0077      0 1
/swapfile       none    swap    sw      0       0
ubuntu at ubuntu:~$ free
               total        used        free      shared  buff/cache   available
Mem:          973740      220844      635872        1112      195784      752896
Swap:        1048572           0     1048572

Title:
  [SRU] add swap file or partition to LicheeRV preinstalled image

Status in livecd-rootfs package in Ubuntu:
  Invalid
Status in livecd-rootfs source package in Noble:
  Fix Committed

Bug description:
  [ Impact ]

  A kernel upgrade from linux-allwinner 6.8 to linux-generic 6.17 fails
  due to the limited board memory (512 MiB) on the LicheeRV Dock. The
  Allwinner Nezha D1 is also memory constrained.

  Add 1 GiB of swap space.

  Both boards use the RISC-V RVA20 ISA and are not supported in
  Questing, Resolute.

  [ Test Plan ]

  Create and boot a preinstalled LicheeRV and a Allwinner Nezhal D1
  image.

  Check that /etc/fstab contains a swap entry.

  Run the `free` command to check the swap space.

  [ Where problems could occur ]

  The change might impact other images or even result in build failures
  if done incorrectly.

  [ Other Info ]
