From 6c27a98c6a5207a29bffaeeb486479a2c24cd26c Mon Sep 17 00:00:00 2001 From: Sam Thursfield Date: Fri, 10 Nov 2017 11:25:31 +0000 Subject: Add minimal-system-image-x86_64 This element produces a disk image that boots in QEMU. It has a kernel, BusyBox, and little else; but should be suitable as a basis for more grand endeavours. This disk image we produce is 53MB. I spent a while trying to get this as small as possible and this is as far as I got: * The boot partition seems to have a minimum size just over 32MB; lower than that and SYSLINUX fails to write the boot sector. The combined size of the initramfs and kernel is about 32MB, so I imagine that's what limits us. * The main partition is limited in size only by the amount of binaries that we put there. * We have a useless 40KB swap partition, which the x86image plugin insists on creating for us. Again 40KB is the minimum size that `mkswap` will allow. It's possible to override or modify the x86image plugin to avoid swap altogether but I'm not sure of the best way to proceed. There are a few dependency cleanups in the bsp-generic stack; previously we'd build the whole 'foundation' stack which took ages and wasn't needed at all. --- elements/deploy-tools.bst | 10 ++++++++++ 1 file changed, 10 insertions(+) create mode 100644 elements/deploy-tools.bst (limited to 'elements/deploy-tools.bst') diff --git a/elements/deploy-tools.bst b/elements/deploy-tools.bst new file mode 100644 index 00000000..84de2e7f --- /dev/null +++ b/elements/deploy-tools.bst @@ -0,0 +1,10 @@ +kind: stack +description: Deployment tooling + +depends: +- core/e2fsprogs.bst +- coreutils-common/coreutils.bst +- deploy-tools/mtools.bst +- deploy-tools/parted.bst +- bsp-generic/nasm.bst +- bsp-generic/syslinux.bst -- cgit v1.2.1
