This is the official release announcement for IPFire 2.17 – Core Update
96. This update comes with many smaller changes and security fixes.

Ramdisk usage change

IPFire uses round-robin databases to collect system data and generate
beautiful graphs. The databases have usually been kept in memory. This
change was made in early versions of IPFire to keep the amount of
writes to the block device to a minimum. However, the number of the
databases has been growing and many systems don’t have enough capacity
in memory. The objective was also that ordinary flash storage is quite
slow. These systems are now however less commonly used which makes this
change unnecessary.

To give an example, many of the ALIX boards use very slow compact flash
storage and do only have 256 or even 128 MB of memory. So neither is
really an option. Systems you will purchase today usually come with
fast SSD storage and a few gigabytes of memory. So both is a viable
option to store these databases.

New installed IPFire systems will now only use the persistent storage
to store these database files. All updates systems will stick with the
old behaviour if they have about 512 MB of RAM or more. Otherwise
upgraded systems will also fall back to the persistent storage.
