With the tuned package now missing on current Amazon Linux: Which cost-efficient simple alternative exists to persistently store Linux configurations for /sys/kernel over a reboot? I see the sysfsutils package exists, but that's a different one than the identically named on Ubuntu where that package uses configuration files below /etc/sysfs.d for permanently modifying settings below /sys/kernel and the AL2023 version doesn't offer that functionality.

I'm now continuing with the solution as simple single-file system service as that works fine. Using the following systemctl service parameters to get it set early enough before apps are started:

[Unit]
Requires=local-fs.target
Before=network.target
[Service]
Type=oneshot
RemainAfterExit=true

If anyone knows better ways to persistently easily configure Linux /sys settings please comment.

If anyone knows better ways to persistently easily configure Linux /sys settings please comment.

You can use tmpfiles.d for this task.

1st example:

cat <<'EOF' | sudo tee /etc/tmpfiles.d/ksm.conf

w /sys/kernel/mm/ksm/run - - - - 1

EOF

2nd example:

cat <<'EOF' | sudo tee /etc/tmpfiles.d/custom.conf

w /sys/kernel/mm/transparent_hugepage/enabled - - - - madvise
w /sys/kernel/mm/transparent_hugepage/shmem_enabled - - - - advise
w /sys/kernel/mm/transparent_hugepage/defrag - - - - never

EOF
