[...] Perhaps the installer could warn of low memory when it starts, differentiating the type of media used (full vs net). The Net media needs more than I gave it, but the DVD works fine on 768MB.
Yes, we can do that since at least 1998¹. Linuxrc has some parameters to tune behavior depending on available RAM:²
MemLimit Amount of free memory in kB below which linuxrc will ask the user to set up a swap partition. MemLoadImage Amount of free memory in kB below which linuxrc will not copy the root image into RAM. MemYaST Amount of free memory in kB below which linuxrc will start YaST in text mode.
Small correction, MemYaST is "Amount of free memory in kB below which linuxrc will ask the user to set up a swap partition before starting YaST."
MinMemory Amount of memory in kB below which linuxrc will refuse to start. Defaults to 0.
The values are defined in this file AFAICT: https://github.com/openSUSE/installation-images/blob/master/data/initrd/them...
The settings can also be passed to linuxrc on the command line when booting. So should be fairly easy to run a set of installations with different amounts of memory from DVD and NET images to check what the limits are nowadays. Carlos, since you have the problem at hand, would you like to help with that?
Sure. But not this week, I'm not at home :-)
I understand you want to try several installations with different memory ammounts, right? Which ammounts? I already know that 3/4 a GB
You have to try how low you can go. The lowest amount possible is when the boot loader can't load kernel and initrd anymore or linuxrc crashes at startup. When linuxrc or YaST start but crash later, passing values for the above mentioned parameters should make linuxrc create swap and allow to continue the installation. Maybe Steffen can has some hints how to find out how to tune MemLimit, MemLoadImage and MemYaST?
makes the net install to fail, yast processes get killed, but works with the full dvd install in graphics mode.
Perhaps a table of tests to do?
Yes, a table could help to visualize the result. cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.com/ SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
