So far the space and free limits (SPACE_LIMIT and FREE_LIMIT config variables) imposed on snapshots handled by snapper had to be provided as a fraction of the whole file system size.
On user request it is now also possible to specify absolute sizes:
# snapper get-config Key | Value ------------------+--------- FREE_LIMIT | 5.5 GiB SPACE_LIMIT | 15.2 GiB [...]
Note that the values must always be provided in the C locale, so with a period as decimal separator and untranslated unit.
This feature is available in snapper since version 0.9.0.
