I tested installation from the provided ISO.
Installation process runs fine, also on ZFS and ZFS on root.
Main problem is with APT mirrors, seems that many are not working.
httpredir mirror should be selected as default for kfreebsd
There is also a problem when changing keyboard language.
For example, I select italian layout.
The problem is related to filesystem mount at startup.
I use a separate / /usr /var /home since the beginning of time
/etc/init.d/keyboard-setup fails ate startup because runs before mountall
/etc/init.d/keyboard-setup calls /bin/setupcon
/bin/setupcon calls in turn /usr/bin/ckbcomp which is not available at startup, before mountall
I am sure not many people will run kfreebsd on separate /usr, but I think that setupcon and ckbcomp which both belong to console-setup should live in same directory
For all the rest, congratulations for great work!
kFreeBSD is in amazing good shape!
