Bug 737917

There are not many services as it's a desktop machine so basically no server daemons started and the services in 11.4 and 12.1 are basically the same.

Please let me know which information is needed and how to get it.

first, install systemd update from home:fcrozat:systemd / systemd (it fixes some issues there).

Second, check dmesg to see if there is any timeout appearing (you might want to boot with systemd.log_level=debug systemd.log_target=kmsg to get a debug trace in dmesg).

Third, try to run :
systemd-analyze blame (to find which service is taking a lot of time)
systemd-analyze plot > boot.svg to see a bootchart of your system booting.

From dmesg:
[   12.920959] udev-configure-printer[860]: failed to connect to CUPS server; giving up
[   12.921502] systemd[1]: Received SIGCHLD from PID 860 (udev-configure-).
[   12.921525] systemd[1]: Got SIGCHLD for process 860 (udev-configure-)
[   12.921567] systemd[1]: Child 860 died (code=exited, status=1/FAILURE)
[   42.720184] usblp0: removed
[   42.720575] systemd[1]: dev-usblp0.device changed plugged -> dead
[   42.720597] systemd[1]: dev-usb-lp0.device changed plugged -> dead
[   42.720607] systemd[1]: sys-devices-pci0000:00-0000:00:13.5-usb1-1\x2d4-1\x2d4:1.1-usb-lp0.device changed plugged -> dead

Looks like a jump here.

I do not have any crypto partition and no LVM.
I got a softraid on the machine but it's not used from 12.1 yet.

bootgraph

cryptsetup / lvm taking time should be fixed with pending maintenance update for systemd in home:fcrozat:systemd / systemd. Please install this package and check again.

I'd suggest opening a bug against system-config-printer which should wait for cups to appear (I guess).

ntp is also taking a lot of time to startup..

bootgraph2

New bootgraph. The printer issue is gone apparently?
Anything looks out of tolerance here? Still NTP?

md.service is taking a lot of time but I'm guessing you have MD RAID on your system ?

for NTP, I can't really say if it is normal for it to take so much time or not.

I run one MD RAID on the system, yes. I also cannot tell about NTP but I wouldn't expect it to take much time.
As the biggest issues are gone with the update and we are basically at the same time of booting as with sysvinit feel free to either close this bug as fixed with the (upcoming?) update or let someone check about NTP.

let's close it as fixed then .
