Title: max_loop=255
Post by: Guy on October 06, 2009, 06:13:40 AM

Can I leave out "max_loop=255" from grub in Tiny Core 2.4, or do I still need to have it in?

Depends on how many extensions you are planning to mount (loading extensions to RAM do not use loop device). Default value is 80, you may need more but this is up to your TC use.

I would keep it, it doesn't use much resources.

I got the idea that the default value has changed from 80 to 255 in the latest version. Am I wrong?

No, it hasn't been changed, yet at least.

This is why max_loop=255 boot option is there.

I found where I got this idea.

Release Candidates -> tinycore_2.4rc1

one of the changes

* Updated /dev/loop to 255 loop devices.

http://forum.tinycorelinux.net/index.php?topic=3083.0

If I look in /dev/loop, there are now 255 loop devices.

In light of this, can I leave out "max_loop=255" from grub in Tiny Core 2.4, or do I still need to have it in?

Yes, it is still needed, if you need over 80 loops. The devices being there is just for convenience, their existence doesn't guarantee the kernel has those devices (ie. I could create hda, hdb, hdc, hdd and still not have four disks)

Thanks for your answers.

With this latest version I am installing all extensions again, as so many are being changed.

I am running with the minimum, as more will be changed over the coming weeks.

I figured it is quicker to ask than to download 80 extensions.

You can check which extensions have been updated (and update them) with the TCE update tool. Boot in "base norestore nolocal", and either run the tool from the menu, or in text mode as "upgrade_tce.sh".
