ramdisk (size, allocation, ...)
I have read a bit about creating a ramdisk.
However some questions I could not find an answer for:
1. There is always talked about the ramdisk_size that you have to specify at boot. But how can I determine what the max size can be?
2. I added the part in the grub config and when I create a filesystem I seem only to be able to make disks of the size specified with the boot loader (so not lower; I thought there would be some more flexibility). Is this correct or am I missing something?
3. By default I see different /dev/ramX files. Is the space for these already allocated? Or does that only happen when I do an mke2fs?
Thanks in advance!
