	Slack shouldn't do any logging (or any other writing) at all to the CF if it's 
mounted read-only, should it? That's the plan, anyway, which should also mean 
that it doesn't ming losing power without being unmounted and also it won't do a 
time-consuming file-system check every time it boots. Quick booting is another 
of my criteria.

	Yes! Embedded is really what I want, except that it seemed more cost-effective 
to use a standard desktop-PC motherboard and other parts. Size isn't critical 
but quick booting, resilience to power removal and reliable unattended operation 
all are.

	I suppose that the thing I most want to know is how fast the PC will boot with 
CF as the storage medium. I've heard that they're VERY slow but I don't know 
whether that's a reliable opinion.

ACPI problem

Hello everyone

I am running Slackware 10.2 (kernen version
2.6.13-Emon08). It is a custom compiled kernel. I
can't get ACPI working; the power switch doesn't turn
off my PC!! I have got acpid-1.0.4-i486-2 installed
and during bootup my PC displays the following message

**************
Starting ACPI daemon /ser/sbin/acpid.
**************

So I tried this

**********************

Regardless of how many times I press the power button,
it just keeps showing me the above 8 lines of output

 It will attempt to log to wherever things like /etc/syslog.conf tell it to.
 Systems like Slax and Knoppix tend to "log" to a file in RAM.
 It all goes away when power does.

 If the system is configured correctly, yes, just like a LiveCD.
 Shutdown on the stuff I do, is virtually non-existant. Just power off.
 It's all ephemeral anyway, so a "proper" shutdown is irrelevent.

 Once I know the system is what I want it to be, I remove the fsck stuff and
 take it out of the boot scripts also, because it's truly unnecessary.
 Since nothing is ( or can be ) written back to CD, there's no point.

 One one I did, it's possible to mount a real hard drive under the virtual
 file system, and in this case, simply powering off is a bad idea, without
 first unmounting the hard drive.

Try re-compiling with the ACPI_BUTTON option as a module and then 
modprobe/insmod it  <at>  boot.

Re: Running Slack from CF-IDE adaptor

You need to do both read-only and no-timestamp... even though data is 
read only, metadata could change, thus  updating the CF data.

mount -o ro noatime

Re: Running Slack from CF-IDE adaptor


Well, a CF on an IDE adapter will be seen just like an ordinary hard disk,
but the CF card will die after... umm.. well, I guess 1 week at best,
probably sooner due to cell wearout from I/O. Flash only takes 100000
rewrites at best, even minix can do that within no time.

But, you might have heard of the firewall Linux IPCop - was Slack based once
iirc and now is LFS based, but anyway, there's a mkflash script that adapts
the logging and such so it's written into a ramdisk and synced every two
hours with the flash module.

Should be a start.

Yes - that's a huge help and was exactly the sort of guidance I was 
hoping for. I'll work through the ideas and see what gives.

Thanks again,

bash, konsole, line wrapping


What is this? in Konsole sometimes lines are not properly wrapped, like
there's no line feed and the beginning of the original line gets overwritten
instead and when moving the cursor back the line is shifted one char to the
left and the like.

 Good deal !
 I actually started nosing around a bit, and although I have the ability
 to create and write flash, I don't have a test machine to boot from it !

 I, too, am starting to see a market for a solid state machine, no moving parts
 in my area of expertise.
 That means that after I find an i386 based system with no fans and such,
 no hard drives, no CD, but with serial and ethernet, and probably with
 plugs for video, keyboard, and monitor, I'll be acquiring a flash/ide adapter,
 but I'm not there yet.

I haven't really followed this thread, so forgive me if I say
something already said. For hardware, you might want to look at:
