Systemd boot messages

Just changed from Arch to Endeavour on an Acer Aspire 5734Z labtop.
Bios does not use UEFI and partition table is MBR

systemd-analyze
Startup finished in 3.132s (kernel) + 6.042s (initrd) + 22.982s (userspace) = 32.157s
graphical.target reached after 22.978s in userspace

I’m going to tweak systemd for a faster boot, however output of
systemd-analyze blame
contains a large 253 entries, many of which are probed tty ports and disk partitions.
Where does the probing take place?
Is there some way of preventing unused hardware from being probed?

If possible can I suppress the lines in systemd containing the partition and tty ports?
In Arch linux I only had about 40 lines output from systemd-analyze blame

Thanks in advance.

That changed in a systemd version introduced last year. I am sure your Arch system was the same if you had run systemd-analyze blame since the update.

Either way, it isn’t making your boot longer.

If you want to see what is actually consuming your boot time you should start with systemd-analyze critical-chain

Thanks Dalto, that was fast!

systemd-analyze critical-chain

graphical.target @23.277s
└─lightdm.service @23.081s +164ms
  └─systemd-user-sessions.service @22.954s +55ms
    └─nss-user-lookup.target @23.280s

Output is a lot briefer, I may be expecting too much for a Pentium T4500 dual core,
4G RAM and a SATA hard drive.

Possibly an issue waiting on a network device?
