345 but they are exclusively used when determining file ownership which is why they
346 are called "filesystem ids". They are usually identical to the uid and gid of
347 the caller but can differ. We will just assume they are always identical to not

564 ``chown()``. For example, they could change ownership so that ``dir`` and all

875 they also work when both the caller and the filesystem use the initial
880 storage. At home they have id ``u1000`` and all files in their home directory
881 are owned by ``u1000`` whereas at uni or work they have login id ``u1125``.
883 Taking their home directory with them becomes problematic. They can't easily
884 access their files, they might not be able to write to disk without applying
885 lax permissions or ACLs and even if they can, they will end up with an annoying
