IPFire 2.17 - Core Update 96 is available for testing
by Michael Tremer, December 22, 2015


this is the changelog of the recent Core Update 96, which has just been uploaded to the testing tree. Please give it a good test over the holidays and don’t forget the bug reporting.

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.
