Hello
I'm currently on my way to get TC4.4 running on my Libretto 100CT (8GB SSD, 64MB RAM, 1,5MB VGA RAM, P166MMX).
Two issues:
a) as OnBoot (as OnDemand works only partly via ssh or busybox) consumes a lot of ram just to be installed (after gcc, alsa, mplayer, my RAM is full) is the boot switch "local=sda2" my way into a traditional installation (meaning, files loaded from disk, no loopback, no reset, no backup)? And is it possible to say local=sda2/whatever ?
b) under NT4 I get the disk running in MWDMA2 mode (the max what the Libretto controller support), in FreeBSD the kernel choses PIO4 and only after atacontrol is initialized it choses MWDMA2, in TC (I guess Linux in generell) I get only PIO1 working which is a bit slow on a 95MB/s SSD; 16 would be nice... When using hdparm I get an error while applying -d=1 saying it's not supported by the device and -p=4 (afair) says the same to my /dev/sda. Any hints?
Cheers

Running root from hard drive is not supported.

a) maybe better try oss instead alsa to reduce memory usage and move gcc to ondemand?
b) can try booting with libata.force=1.00:mwdma2 kernel parameter (see here (http://lkml.indiana.edu/hypermail/linux/kernel/0904.2/03739.html) and kernel params (http://kernel.org/doc/Documentation/kernel-parameters.txt))

Just wondering if having this feature http://forum.tinycorelinux.net/index.php/topic,12856.msg70508.html could solve onboot issue?

Unionfs is not a magic bullet for ram use, IIRC it did not differ much from symlinks.
Even worse, when unionfs runs out of ram, you don't get an "out of ram" message, you get an oops...
-
Well, the symlinks don't take *that* much space anyway. Could it be the overhead of squashfs caches?
-
i also think that need to allocate some ssd space for swap

Hi
maybe; I'm quite used (and forced) to a traditional /usr folder and unpacked drivers/bins/...
I'm not into onionFS, so I'd not been able to integrate it into my system.

Hi
I'm aware of it, but a /usr would suffice for most of my needs. I'm willing to install about 20-30 Apps, sizing from 1MB-50MB; loopbacks cost lots of my dear RAM...

Hi
I already have 160MB on a special Swap Partion, just to be able to start; when ALSA is installed "onboot" I'm nearly out of memory (I'll going to OSS as I did in my FreeBSD Disk); X would take the rest. Even when I'm willing to sacrifice X or ALSA, or Browser: it would be fine to have a stationary folder for emacs, mplayer, mpg123, gcc, ddrescue, openssh, which do not need real performance (for MP3/OGG/FLAC decompression) but do not consume too much RAM.
Cheers

Make sure you don't have the copy2fs.flg file in your tce directory.

Hi Gerald
is it possible to inject files to the /usr/.... folders, including 'em into the filelist and then having user apps like mplayer, ... ready after a reboot? I'm not so far into the mechanismn of TCL and it's filehandling (Ondemand); I want to get rid of alsa's (File=RAM) size (and others). What are the drawbacks of inflicting into the clear way of TCL's App Handling?

That worked well; I was amiss with the exact syntax as the bootlist is quite generic.
-
He's not saying it's not possible, just that it is not supported. The same applies to your current question.
-
i don't quite understand so libata.force kernel parameter is works or not?
-
Hi AbNoRMiS
yes the parameter (=libata.force=1.00:mwdma2) worked as promised. Now it's running in MWDMA2 and not PIO4 as before.
Cheers

make onboot.lst like this
Xvesa.tcz
Xprogs.tcz
jwm.tcz
wbar.tcz
OSS.tczimmediately after system boot with these configuration will employ about 20mb memory
all further extensions such as mplayer, browser etc can install as ondemand
and they will not take time during boot and not take memory until start them
and you do not have to include usr folder to backup
all current data of these extensions are written in home folder
and will be backed up during reboot and will be ready after reboot

Hello Abnormis
my list is quite small bu I need samba at startup to connect my CIFS shares via fstab and ALSA; a few OnDeamnd I tested only works when installed Onboot as well. I'm still on a workaround to install statically usually used programms.
Currently I'm out of time
Cheers

Hi sam.vanratt
Are you looking to share files or access files on another machine? If you just want to access files on another
machine, cifs-utils.tcz will do that.

Hi Rich
if I can use mount.cifs (via fstab) that's enough and should significantly lower the RAM usage. I'll try it in about a week or so and report back
Cheers
Sam
