In other situations we do not want to remove power, but rather halt so that control is then handed to the H/W watchdog, which will do a full reset of everything. I was also thinking of laptops whan I added this. (see the commit message) We'd be really thrilled if someone changed the semantics out from under us...... RB_POWEROFF does exactly that. RB_HALT does NOT do that. The processor either executes a HALT instrauction, or enters a type loop. Alternatively it might go to a firmware monitor, but we don't have that. what the 'shutdown' instruction does is arguable, but my personal feel is that it should require an argument to make it power off. Just like it requires an argument to make it reboot. On Sun, 13 Dec 1998, Terry Lambert wrote: > > : > > shutdown -h. What is wrong with this? > > : > > > : > It is wrong. > > > > Why?
