knowing how is booted the server (single user or multi user)

[maccarone]

All,
Looking inside messages file I'm not able to know if boot was executed in single user mode or not, the boot sequence seems to be the same.
How is possible to know if a specific boot was executed in single user mode?
Moreover, all command executed in single user mode are not reported inside .sh_history file.
Is there a way to know which commands have been executed in single user mode?

Thanks

Massimo
