zRAM

Sun Jun 9 07:08:19 UTC 2013

Ok a simple suggestion from me. Why don't we decidebto enable zram (with zram-config) for the alpha version and see how itnworks out for the testers. We can disable this afterwards if the test fails. 
But I highly doubt that you will see any downside in using zram. 
And btw. as I don't think it os clear to everyone zram enabled means a virtual swap partition gets mounted into the system. The location of this swap partition is however instead of the traditional one a virtual compressed ram drive. I hope that this is understandable. 
Please +1 if you also want zram enabled by default in the alpha images.

I have found that a swap partition can help installing when there is low
RAM. If there is already swap on the internal drive, it will be grabbed
by the live system (and it's installer will benefit from it). I have
even made a version of the Lubuntu-fake-PAE with swap on the USB drive
for the same reason, 'grub-n-iso-n-swap'.

I guess zRAM can have the same effect, to allow more data to be managed
by the memory system with a given amount of RAM hardware.
