Hi, what is $SUBJECT doing and how to debug that in more detail? On one of my systems it takes 1min 4.209s systemd-udev-settle.service at boot time which is a bit annoying. That is on TW latest on a pretty common Intel system (i5-4570, 16GB RAM, SSD) Any hints? Thanks, Wolfgang

I don't have specifics on systemd-udev-settle.service, but generally when these type of delays show up, I start poking around /etc/sysconfig and in the various /usr/lib/systemd/system/systemd-udev* files to see if there is a timeout specified. (I had a similar issue with wlan0 and cut 40s off boot time just by reducing the timeout (from 51s to 11s total)) I'm guessing, but I suspect systemd-udev-settle.service works for 4.209s and then gets stuck on some 60s timeout somewhere. Hopefully somebody else that knows will chime in and help narrow it down. -- David C. Rankin, J.D.,P.E.

Searching for 'linux systemd settle' got me a pointer to the man page for systemd-udev-settle.service, though it's not installed on my machine. https://www.man7.org/linux/man-pages//man8/systemd-udev-settle.service.8.htm... Felix says he has disabled it on his systems because, as the man page says, it's not recommended that it be used. Leslie -- openSUSE Leap 15.2 x86_64

systemctl mask systemd-udev-settle.service
Why/how is it enabled in the first place if it is recommended not to be used?

Found it meanwhile (somewhat): systemd[1]: Starting Wait for udev To Complete Device Initialization... udevadm[479]: systemd-udev-settle.service is deprecated. Please fix wickedd.service not to pull it in. systemd[1]: Finished Wait for udev To Complete Device Initialization. Pretty clear advice ;-) What are the wicked people saying? Should it be fixed or not? Wolfgang

systemctl mask systemd-udev-settle.service
I thought masking was supposed to be done after stopping and disabling? My method, in order: # systemctl status <service> # be sure no typos, then <ENTER> # systemctl stop <service> # <UP>, remove status, type stop, <ENTER> # systemctl disable <service> # <UP>, remove stop, type disable, <ENTER> # systemctl mask <service> # <UP>, remove disable, type mask, <ENTER> I suppose YaST should offer this as well, but I see no edit button there (in 15.2). -- Evolution as taught in public schools, like religion, is based on faith, not on science.
