--- Comment #2 from Yunhe Guo <guoyunhebrave@xxxxxxxxx> ---
The snapper document says it has a 0.5 snapshot space setting by default. This
means on a default openSUSE installation, 40 GB root partition only has 20 GB
available, and other 20 GB spaces will be used by snapshots in future. 20GB is
not a safe size for openSUSE desktop I think. You know, before we have Btrfs
and Snapper, we have 40GB root partition by default, and I have never filled it
up by install packages and update. But when we introduced Btrfs and Snapper,
the space is not enough for some users.

So my suggestion is, openSUSE installation should always consider partition
space and snapshot space together and ensure here is enough space for
installing packages.

If root partition is 40GB, the snapper settings should be smaller, maybe 0.3
instead of 0.5. If the root partition is 60GB, 0.5 is probably okay. Default
root partition size should also be increased to ensure that except snapshot
space, here is still 30GB or more for system and software. This could reduce
the chance of filling up root partition, which may cause critical data lose or
system failure.
