3) swapon --verbose /swap.img enables swap file successfully
4) swapon returns error, says swapfile has holes.
----
Curtin creates file-based swap files with fallocate:
fallocate -l XXXM /swap.img
When booting Groovy (5.8 kernel), the swapfile fails to load, complains
it has holes
root@ubuntu:/home/ubuntu# swapon --verbose /swap.img
swapon: /swap.img: found signature [pagesize=4096, signature=swap]
swapon: /swap.img: pagesize=4096, swapsize=1251999744, devsize=1251999744
swapon /swap.img
[ 178.283022] swapon: swapfile has holes
swapon: /swap.img: swapon failed: Invalid argument
root@ubuntu:/home/ubuntu# uname -r
5.8.0-18-generic
This configuration works fine on Focal (5.4) and older. Previous Groovy
kernels, (5.7) also worked.
