[SOLVED]Getting Suspend to RAM Working

[nomer]

I'm trying to make so I can suspend my machine to memory. I'm running TinyCore 4.5.3
I've installed acpitools.tcz onboot. I then used "acpitool -W " to allow some devices to wake up the machine. Then I tried "sudo acpitool --suspend". Unfortunately, it spits out this error:

Function Do_Suspend : could not open file : /proc/acpi/sleep.
 You must have write access to /proc/acpi/sleep to suspend your computer.

Sure enough, /proc/acpi/sleep doesn't exist. If I "cd" to /proc/acpi and try "sudo touch sleep" it simply outputs this:

touch: sleep: No such file or directory

What gives? How do I create the file or induce some tool to create it?

did you run acpid?

No, I hadn't orginally.
So I've now installed acpid.tcz onboot. I rebooted the machine, ran "sudo acpid start", added wake up devices, ran "sudo acpitool --suspend", and received the same result.

Hey, I just found suspend-utils.tcz in the repo; maybe I should give that a test.

Huzza! suspend-utils.tcz worked. Here were my steps:
1) remove apcitools.tcz and acpid.tcz from onboot.lst
2) install suspend-utils.tcz onboot
3) reboot
4) run "sudo s2ram" to suspend to ram
5) hit a key to resume

I'll mark the OP "[SOLVED]"

You might want to keep acpid so you can configure one of your buttons to run s2ram.

Acpitools is not up to date with the kernel. The control files are nowadays at /sys/power.

edit: We also seem to have the latest version of it, it hasn't had an update in two years.
