我从来都是用的init 0

它们之间有什么其别呢?
谢谢!

$ whereis poweroff
poweroff: /sbin/poweroff /usr/share/man/man8/poweroff.8.gz

$ file /sbin/poweroff
/sbin/poweroff: symbolic link to `reboot'

$ whereis reboot
reboot: /sbin/reboot /usr/share/man/man8/reboot.8.gz

$ file /sbin/reboot
/sbin/reboot: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.8, dynamically linked (uses shared libs), stripped

poweroff应该有sync 而init 0我感觉没有sync
