Does anaconda check package signatures for the netinstall?
I believe so. Checksums are definately checked (RPM won't install a corrupt package).
Does netinstall even work well?
Certainly. I actually haven't installed Fedora (or RHEL/CentOS) any other way in a long time (probably at least 5 years). Just about all of the RHEL/CentOS installs, and some of the Fedora installs, were from kickstart, but most of the Fedora installs were interactive.
For F18 I planned to do netinstalls on a dozen or so desktop workstations and a couple of new servers, using our internal trusted Fedora repo. After specifying our internal repo as the source, netinstall would not allow me to choose the software to install -- all I got was the yellow triangle on the summary page, and blank pages where I should have been able to choose "Gnome desktop", "network server", etc.
I would say that sounds like there was something wrong with your repo.
