The swap space required by a system running Red Hat Enterprise Linux 5
varies according to the role of the system. Previously, anaconda recommended
that all installations on IBM System z required swap space at least equal to
the amount of installed system memory. This recommendation could have misled
users to allocate far more swap space than was required for their purposes.
Anaconda now warns users only if they have not allocated any swap space at
all. Users can therefore allocate swap space appropriate to their systems
without potentially misleading warnings from anaconda.
