Linux systemd 学习总结

simple vs oneshot:

When you are deciding which service type to choose between simple and oneshot, here is some guidance:

• Does your service need to complete before any follow-up services run? Use oneshot.
• Do your follow-up services need to be running while this service does? Use simple.
• Is this a long-running service? Probably use simple.
• Do you need to run this service only at shutdown? Use oneshot.
• Do you need to have multiple separate commands to run? Use oneshot.
