Hi!
When booting a bzImage which is contained in a bigger file, does Grub
load the whole file into memory or does it only load the bzImage from
the file containing it?
Here is some background:
I have a file, say "myimage", which contains both a kernel (bzImage)
and a root filesystem (squashfs). The kernel is configured in a way to
automatically boot into that filesystem.
I am booting the kernel inside "myimage" successfully using the
following command:
linux ($root)/myimage
boot
The root filesystem being contained in "myimage" is currently not huge,
so it should fit into memory, but I am worried that this might change
in the future and I can get an out-of-memory-condition. Therefore my
question at the beginning of this mail.
Thanks!
Best,
Holger
