If it safe to shut down a system, boot from a live CD, delete all disk swap partitions, and boot the system?
This is in follow up to How to safely turn off swap permanently and reclaim the space? (on Debian Jessie).
I thought not Debian, or at least Ubuntu (and descendants) will automatically find all swap partitions on all mounted-at-boot disks and allocate swap correctly by default.
The post asking how to turn off swap has many answer posts that have involved, multi-step processes to turn off swap.
Is simply removing the swap partitions not recommended?
