My question which of these processes are not needed so i can boot faster. No I am not making a server,just normal PC usage.
This information is not enough to make any useful advice. The problem is that while systemd-analyze blame
outlines the services which took the most time to start up, it does not say:
The first question is answerred by systemd-analyze critical-chain
(or, in complex cases, by systemd-analyze plot
). The second question is answerred by systemctl list-dependencies default.target
.
Hence it'd be great if you provided outputs of those commands (except plot
, which outputs an SVG file and is not necessary in most cases).
However, you could try disabling (with systemctl disable
) NetworkManager-wait-online.service
and remote-fs.target
(the latter sometimes pulls in the former). The point is, you almost certainly do not need the network to be up before you can login, and can tolerate the network starting up in background.
