Amazon Linux 2023 introduces changes to how /tmp behaves when compared to Amazon Linux 2.
The default configuration for AL2 was that both /tmp and
/var/tmp were on the root file system. Amazon Linux 2023 defaults
to using tmpfs for /tmp with a limit of 50% of
RAM and a maximum of one million inodes.
These changes bring Amazon Linux in line with the behavior of other Linux distributions.
For full details of the file system layout of AL2023, see /tmp and /var/tmp in the Filesystem Layout section.
