Suspend to RAM...Suspend to RAM...Posted Jul 31, 2008 9:17 UTC (Thu) by rsidd (subscriber, #2582)Parent article: OLS: Shuttleworth on free software development
"[Updating] picked up a new kernel as well and he did a suspend to RAM when he was done; only later in the cab ride to the Congress Centre did he think: "maybe that was a mistake" Why would that be a mistake? His new kernel has been installed on the disk but does not interfere with the old kernel in any way. Now, if he had done a "suspend to disk" and successfully resumed, that would have been interesting...
