[gentoo-user] Differences: halt, shutdown, init 0?

[gentoo-user] Differences: halt, shutdown, init 0?

[Minn M Soe]

Hello,

Is it harmless if we shut down with the command init 0? Are there big
differences between halt, shutdown -r now and init 0?

Thanks!
Minn

Init 0 does a shutdown just without the -r now (which you could add). Here 
is the line from my stock /etc/inittab "l0:0:wait:/sbin/rc shutdown"

See the man pages for 'halt' and 'shutdown'.

Unless told otherwise, shutdown operates by signalling init, so 
"shutdown", "halt", "init 0", and "telinit 0" are all equivalent.  Halt 
calls shutdown if the system is not already at runlevel 0 or 6, so that 
is also normally equivalent.

Read that entry again, what you said is not correct.  For runlevel 0, 
init runs "/sbin/rc" with an argument of "shutdown".  This causes the 
gentoo startup scripts to stop all services, unmount network 
filesystems, etc.  This is not the same as /sbin/shutdown.
