You can indeed make it as large as you want, however, is it advisable? From what I’ve read…I wouldn’t try it. I went for the official documentation. Since it is included in kernels 2.4.x and newer, it would make sense that the documentation would be at kernel.org
What you decide to do however, is your own business. There are always tweaks and tricks that can be done. Experiment and have fun.
You are somehow reading that last sentence (about oversizing) as referring back to the previous sentence (about the default size limit). I’m not seeing any indication that they are intended to be connected in that way. And other parts of that report do seem to suggest that swap is used. If swap+memory is over-committed, I would expect problems. And I think that’s all the last sentence is intending to say.
Happy to hear of your success. You can add Solved to your message title and add it to the tag cloud at the bottom, but the original titl can not be changed by the original poster.
/var/log/? I would never use a tmpfs there. If there is a problem on
your machine there will not be any logs to look at later.
What you might do instead is tell the kernel to delay write operations
and group them. How to do that? Well, I don’t exactly know, but the
laptop-mode-tools (I’m unsure of the exact name, my laptop is powered
off ATM) do it while on battery, so the information can be extracted
from there. I seem to recall a sysconfig file with those adjustments.
/etc/sysconfig/powermanagement ??
/etc/sysconfig/kernel ??
