Short of a serious emergency (e.g., UPS with
30-sec lag and no input power) stick with
'shutdown -fh now'. The main problem is that
you bypass the stop phase of all the app's
started up via init.d; very little short of
just hitting the reset switch or yanking the
power.
if you do it the right way, start with 'e' and 'i', all apps are cleanly
terminated/killed. So if an app does not quit cleanly, it is broken.
The correct sequence is: e,i,u,b/o and it is absolutly save.
Folks, keep in mind why I asked this question in the first place. My
power supply was frying and I needed a VERY fast shutdown. This was not
asked as a fast way to shutdown just because we are impatient or
something. This was for the event of a serious emergency where I needed
a shutdown in just a very few seconds not a minute or two. Some of my
services take a while to stop, foldingathome being the longest one.
Basically, this is not intended to be used to shutdown a puter on a
regular basis, unless you burn out P/S's on a daily basis. O-o
Just didn't want someone to be using this on a regular basis and then
wondering why their system has a new nickname, FUBAR. :'(
