cinit knows of a so called "rescue mode" (other init systems also
|
|
name it "Single user".
|
|
|
|
In this rescue mode you have a shell. Exactly one shell.
|
|
|
|
No getty, no daemon, nothing will be alive, not even cinit.
|
|
|
|
You start the rescue mode either by
|
|
a) sending SIGUSR2 to cinit (kill -USR2 1)
|
|
b) using cservice (cservice -s thilo)
|
|
|
|
You can do maintaining then. When you finished, you can either
|
|
a) hard-reboot/poweroff/halt
|
|
b) restart cinit and restart the system without needing to reboot
|
|
|
|
In the later case, you simply have to replace your shell with
|
|
cinit. In most shells you can do that by entering the following:
|
|
|
|
shell # exec /sbin/cinit
|
|
|
|
This assumes that you left the system in a clean state: Exactly as
|
|
the kernel would start (Well, cinit may ignore if some things are there,
|
|
but do not wonder if some services will fail, if their job is already done.).
|
|
|
|
Oh, and yes, you could even update cinit this way ;-)
