Re: GParted webbooting
To summarize, GParted live 0.20.0-3 amd64 works via PXELinux memdisk, however, it's not for i486 and i686-pae ones. I have to add "vmalloc=256MB" to the boot parameters for i486 and i686-pae release. However, I am not sure if there is any side effect. I tested i686-pae on the virtual machine with 512 MB, booting either from iso or PXELinux, they all worked.
Therefore it looks safe to add "vmalloc=256MB" for i486 and i686-pae ones.
However, booting from memdisk with pxelinux is not used very widely. I believe it's only one in thousands. Especially now amd64 release works, only i486/i686-pae failed. As Ady suggested to me via email, he said the best choice is to have a doc to describe this. I agreed with him.
How about your suggestion?
