SysV/LSB > scripts are officially supported on F15 (and will continue to be > supported for a long time beyond that). but this works only in your small world and on a desktop! one example is a FULLY mysql-driven mail-server * dbmail, postfix, dovecot-proxy, postfix-policyd depends on mysqld * dovecot as imap proxy depends on dbmail-imapd * postfix depends for sasl-auth on dovecot this means explicitly that you have a defined start-order started means in this case: ready for connections processs running is not enough below a well defined and since years working starting order and now tell me how this will work with your blind "i fire up every service as fast as i can to make boot 5 seconds faster" when the result is nothing orks as expected? additionally i have since years watchdog-scripts runnig whaich are restarting services if something went wrong and detecting if "/sbin/service" for the missing service is running or a reboot is requested to prevent blind fire up them - this does not work any longer this way so we come to the next major problem: https://bugzilla.redhat.com/show_bug.cgi?id=714525 it does not really matter for the admin who and why fires up mysqld in this case - if i say "systemctl stop mysqld" i mean this exactly so, everytime in everycase and systemd has to respect this! this start-order is hardly workd out, most services are compiled on an own build-environment to prevent overwriting init-scripts and make sure that exactly this start-order is active, everytime, 365 days and 24 hours a day [root@mail:~]$ ls /etc/rc3.d/ insgesamt 0 lrwxrwxrwx. 1 root root 19 2008-08-18 07:03 K10dc_server -> ../init.d/dc_server lrwxrwxrwx 1 root root 19 2011-05-28 20:26 K10saslauthd -> ../init.d/saslauthd lrwxrwxrwx. 1 root root 19 2008-08-18 07:03 K12dc_client -> ../init.d/dc_client lrwxrwxrwx 1 root root 19 2011-05-28 20:27 K35denyhosts -> ../init.d/denyhosts lrwxrwxrwx. 1 root root 20 2008-08-18 07:03 K50netconsole -> ../init.d/netconsole lrwxrwxrwx 1 root root 16 2011-06-17 02:56 K50vnstat -> ../init.d/vnstat lrwxrwxrwx 1 root root 15 2011-05-28 20:26 K75netfs -> ../init.d/netfs lrwxrwxrwx 1 root root 17 2011-05-28 20:26 K75ntpdate -> ../init.d/ntpdate lrwxrwxrwx 1 root root 20 2011-05-28 20:25 K85messagebus -> ../init.d/messagebus lrwxrwxrwx 1 root root 15 2011-05-28 20:26 K89rdisc -> ../init.d/rdisc lrwxrwxrwx 1 root root 18 2011-05-28 20:25 S08iptables -> ../init.d/iptables lrwxrwxrwx 1 root root 17 2011-05-28 20:26 S10network -> ../init.d/network lrwxrwxrwx 1 root root 16 2009-03-17 10:31 S11auditd -> ../init.d/auditd lrwxrwxrwx 1 root root 17 2011-05-28 20:26 S12rsyslog -> ../init.d/rsyslog lrwxrwxrwx 1 root root 17 2011-05-30 00:45 S14unbound -> ../init.d/unbound lrwxrwxrwx 1 root root 19 2011-05-28 20:26 S26udev-post -> ../init.d/udev-post lrwxrwxrwx 1 root root 14 2011-05-28 20:26 S55sshd -> ../init.d/sshd lrwxrwxrwx 1 root root 14 2011-05-28 20:26 S58ntpd -> ../init.d/ntpd lrwxrwxrwx 1 root root 16 2009-09-20 02:16 S64mysqld -> ../init.d/mysqld lrwxrwxrwx 1 root root 32 2011-05-28 20:27 S79dbmail-postfix-policyd -> ../init.d/dbmail-postfix-policyd lrwxrwxrwx 1 root root 18 2011-05-28 20:27 S79postgrey -> ../init.d/postgrey lrwxrwxrwx 1 root root 18 2009-09-20 00:34 S80vmtoolsd -> ../init.d/vmtoolsd lrwxrwxrwx 1 root root 22 2011-05-28 20:26 S81dbmail-imapd -> ../init.d/dbmail-imapd lrwxrwxrwx 1 root root 22 2011-05-28 20:26 S81dbmail-lmtpd -> ../init.d/dbmail-lmtpd lrwxrwxrwx 1 root root 22 2011-05-28 20:26 S81dbmail-pop3d -> ../init.d/dbmail-pop3d lrwxrwxrwx 1 root root 26 2011-05-28 20:26 S81dbmail-timsieved -> ../init.d/dbmail-timsieved lrwxrwxrwx 1 root root 17 2010-11-24 14:53 S82dovecot -> ../init.d/dovecot lrwxrwxrwx 1 root root 17 2011-05-28 20:26 S83postfix -> ../init.d/postfix lrwxrwxrwx 1 root root 15 2011-05-28 20:26 S85httpd -> ../init.d/httpd lrwxrwxrwx 1 root root 15 2011-05-28 20:26 S90crond -> ../init.d/crond lrwxrwxrwx 1 root root 11 2011-05-28 20:26 S99rc-local -> ../rc.local > Of course, we'd like to see more and more services moved over to native > unit files and I greatly appreciate Johann's and Michał's work on this, > but that is work for F16, and should not be done on an already released > distribution. then the distribution should not have been released with systemd
