F 15 services needed or not which ones???

[jakebpg]

What services are necessary for the proper operation of F 15?
How do you turn off unnecessary services?

The reason for these questions is as of late my laptop has been taking forever to load the OS to the login screen.

It seems to hang on the Plymouth loading screen about 1/2 way through the infinity bubble. I down arrow to eliminate the graphics to see what's going on and all that is there for an extended amount of time is a blank screen and finally I see the boot process starting that is normally seen. Very baffled about what's been happening.
I did search and found this command and the numbers seem to be very high.

systemd-analyze blame

and here are the results:

There are some services that I see right off hand that you disable unless you are actually using them

cups.service (not needed unless you have printers)

abrtd.service abrt-oops.service abrt-cppp.service (not needed unless you wish to use abrt to debug crash reports)

iscsid.service iscsi.service (not needed unelss you have iscsi drives (if you have to ask what they are, then you probably don't have any)

ksmtuned.service ksm.service (not needed unless you are running virtual machines with KVM)

xinetd.service (definitely not needed or wanted unless you are actually using it and have it properly set up - security hole if not properly configured)

nmb.service smb.service (not needed unless you are sharing files with Windows machines (samba server)

smolt.service (not needed unless you wish to grab your machine hardware profile and send it to fedora, I believe monthly)

Any of these services can and should be disabled if you are not actually using them.

Edit:
to disable services: (for example, disable smolt.service)

from console or terminal

su -
(root password)

systemctl disable smolt.service

That will disable it so that it won't start when you boot again.
