Info
 This section collects information about the mtd partitions created during Linux boot. It is gathered from the dmesg output in supportdata, if present, which is a limited ringbuffer. This info 'scrolls out' the log with time, so many supportdata probes lack this information, especially for models with limited ressources. Note that Linux partitions and mtd numbers differ from those in Bootloader-Environment.

Linux-Partitions[edit]

See also the table with FRITZ!OS 7.50+ news below and the total Overview of F!OS news!

Daily updated index of all Linux partitions found scanning Supportdata-Probes. Last update: 2024-12-31 06:53 GMT.
The label (partition) in the Partition column shows there are other objects in this wiki using this name.
The Mod column shows the amount of models using the respective partition. Click the column header to sort by this number.
The label Part in the Type column marks physical mtd partitions, Vol marks UBI volumes.
Note that the list of partitions comes from dmesg output in supportdata, a ring buffer which can loose the info.
