Dear All The target.requires or target.wants contains some soft link. Ex: /lib/systemd/system/obmc-host-startmin@0.target.requires lrwxrwxrwx 1 root root 31 Nov 29 2019 obmc-chassis-poweron@0.target -> ../obmc-chassis-poweron@.target lrwxrwxrwx 1 root root 25 Nov 28 09:51 op-occ-enable@0.service -> ../op-occ-enable@.service lrwxrwxrwx 1 root root 22 Nov 28 09:57 start_host@0.service -> ../start_host@.service Now, I want to add or delete soft link:op-occ-enable@0.service I can use "rm -rf ./op-occ-enable@0.service" to achieve the goal. But,I'm not exactly sure this is formal operation. And I'm afraid this will be side effect. Are there other tools or formal methods to do this? Best regards Felix
