I just installed Alt-F 0.1RC5 on a DNS-321. It seems to be working fine. (Thanks for making this available!)
I had previously installed ffp and optware on the server. I built a couple opt packages (arp-scan, dnsmasq). Both ffp and opt packages worked.
Before installing Alt-F, I renamed ffp to ffp-orig, per directions. After the install and initial setup, I renamed ffp-orig back to ffp and rebooted. The Alt-F Package Manger page did not display any of the Alt-F packages, After resetting -x permissions on the ffp/start scripts, the Alt-F Package Manager now works correctly. (Looks like something that ffp started was stepping on Alt-F.)
None of the optware packages appear to work: they need libc.so.1, which is not found, as well as some other libraries.
The Available ffp Packages link shows that there are many more packages available, but there isn't any hint how to install them. When I run slacker (from my old install), it doesn't show any installed packages. It aborts when listing available packages. (I also installed ffp-0.7 from Alt-F. This doesn't contain slacker.)
How can I install additional ffp packages?
