So, merge two files manually, preserving your local changes. As you can see, /etc/apache2/2.4/conf.d/modules-*.load files have gone, and you have to include LoadModule directives either in /etc/apache2/2.4/conf.d/*.conf files or in /etc/apache2/2.4/httpd.conf directly

Hi AlP,

I have ATM (after /hoipster was upgraded this morning):
:; svcprop svc:/network/http:apache24 | grep ^httpd
httpd/stability astring Evolving
httpd/startup_options astring ""
httpd/server_type astring worker
httpd/MPM astring event
httpd/value_authorization astring solaris.smf.value.apache

And my apache does not start:
:; tail -6 /var/svc/log/network-http:apache24.log
[ Mar  4 08:52:53 Enabled. ]
[ Mar  4 08:53:01 Executing start method ("/lib/svc/method/http-apache24 
start"). ]
Apache version is 2.4
/usr/apache2/2.4/bin/apachectl[87]: /usr/apache2/2.4/bin/httpd.worker: 
not found [No such file or directory]
Server failed to start. Check the error log (defaults to 
/var/apache2/2.4/logs/error_log) for more information, if any.
[ Mar  4 08:53:01 Method "start" exited with status 95. ]

And indeed:
:; ls -al /usr/apache2/2.4/bin/httpd.worker
ls: cannot access '/usr/apache2/2.4/bin/httpd.worker': No such file or 
directory

:; ls -al /lib/svc/method/http-apache24
-r-xr-xr-x 1 root bin 2,4K Mar  4 08:47 /lib/svc/method/http-apache24

(so method script tries to start no-existing binary...)

FYI: I was using worker model for last couple of years...

With best regards.
