I do not think masking is right for now, however I'd like to chime in
given there is work around this.
The current ipactl method was necessary due to issues in using systemd
fully, however if newer systemds have bugs about enabling/disabling unit
files from another one fixed then we should look into making the
ipa.service use ipactl *only* to enable/disable unit files.
This way if we can create the various unit files as eg:
ipa-httpd.service where the only thing we do is add an After:
ipa.service and then include the system's httpd.service file we will be
in a better situation.
Especially on shutdown, as no matter what changed in LDAP on shutdown
we do not even lookup anything and just let systemd tear down all
services in the ipa group (I guess there is a way to tell systemd that
if ipa.service goes down all it's dependent services also need to go
I know this is a major refactoring, but if we can pull it off, this is
the correct way to go with systemd integration in the longer term.
