Hello all,
with thin provisioning available, the total and free space values
reported by a filesystem do not necessarily mean that that much space
is _actually_ available (the actual backing storage may be smaller, or
shared with other filesystems).
If your package reports disk space usage to users, and bases this on
filesystem free space, please consider whether it might need to take
LVM thin provisioning into account.
The same applies if your package automatically allocates a certain
proportion of the total or available space.
A quick way to check whether your package is likely to be affected, is
to look for statfs() or statvfs() calls in C, or the equivalent in
your higher-level library / programming language.
