Yes but what is the point of "starting" ipa.service "after" its own
components ?

I can understand putting there the following:
 * network.target
 * certmonger.service
 * messagebus.service

I do not understand putting there these:
 * dirsrv.target
 * pki-tomcatd@pki-tomcat.service
 * pki-cad.target
 * httpd.service
 * krb5kdc.service
 * kadmin.service
 * ntpd.service
As these are started by ipa.service itself

I am not sure why these are put there either:
 * nslcd.service
 * nscd.service
 * portmap.service
 * rpcbind.service
 * sshd.service
 * autofs.service
 * rpcgssd.service
 * rpcidmapd.service
 * chronyd.service
Why do we need to be started after these ? We have no direct dependency.
Besides we do not use nslcd, nscd, chronyd at all when installing
freeipa as we replace all of them with sssd (actually not listed at all)
and ntpd

Also why nfs and the rpc stuff should be started earlier ?
rpcgssd in particular may try to kinit with the nfs keytab, so starting
it before the kdc wouldn't work well.

Simo.
