Here's an interesting bug to watch out for:
I spent a while today trying to install a fedora 29 x86_64
workstation in a virtual machine using the live image and
install to disk:
https://bugzilla.redhat.com/show_bug.cgi?id=1652092
I reported that as a virt-manager bug, but I'm thinking it
is really an anaconda bug. The custom partitions I tried
to create always hung during the installer disk formatting
phase.
I worked around it by using the "advanced" custom partitioning
tool instead of mere "custom", and with the exact same partitions,
it zipped right through formatting and did the install.
