In the file `/etc/log2ram.conf`, there are five variables:
- `SIZE`: defines the size the log folder will reserve into the RAM (default is 40M).
- `MAIL`: Disables the error system mail if there is not enough place on RAM (if set to `false`)
- `PATH_DISK`: activate log2ram for other path than default one. Paths should be separated with a `;`
- `ZL2R`: Enable zram compatibility (`false` by default). Check the comment on the config file. See https://github.com/StuartIanNaylor/zram-swap-config to configure a zram space on your raspberry before enable this option.
- `USE_RSYNC`: (commented out by default = `true`) use `cp` instead of `rsync` (if set to `false`).
- `MAIL`: disables the error system mail if there is not enough place on RAM (if set to `false`).
