chown administrators.none /etc/ssh_host_rsa_key*
chmod 777 /etc/ssh_host_rsa_key*
Then with StrictModes enabled, sshd will start and run just fine (running as system). But if I then do
chown system.none /etc/ssh_host_rsa_key*
Then sshd fails to start. But I (think I) recall that in the past the protection had to be tight and the owner had to be system for sshd to start? Am I remembering correctly?
Thanks,

You're right that PermitUserEnvironment should be added to ssh-host-config.
But it's set to no by default, so you have to change it anyway.

auth.c, line 378ff:
if (options.strict_modes &&
(stat(user_hostfile, &st) == 0) &&
((st.st_uid != 0 && st.st_uid != pw->pw_uid) ||
(st.st_mode & 022) != 0)) {
log("Authentication refused for %.100s: "
"bad owner or modes for %.200s",
pw->pw_name, user_hostfile);
The above code checks the mode additionally to the user id so what's
gentler here? Or do you mean another piece of code?
