Enclosure LED Utilities
ledmon and ledctl are userspace tools designed to control storage
enclosure LEDs. The user must have root privileges to use these tools.
These tools use the SGPIO and SES-2 protocols to monitor and control LEDs.
They been verified to work with Intel(R) storage controllers (i.e. the
Intel(R) AHCI controller) and have not been tested with storage controllers of
other vendors (especially SAS/SCSI controllers).
For backplane enclosures attached to ISCI controllers, support is limited to
Intel(R) Intelligent Backplanes.

+Subject: [PATCH 1/2] Replace nonstandard on_exit() function by atexit()
+
+on_exit() is not portable and not available on the C libraries musl
+and uClibc.
+
+So let's replace it with standard atexit() function.
