similar to: [PATCH supermin 0/5] Make supermin mini-initrd quieter and faster.

DAX is explained in detail here: https://lwn.net/Articles/610174/ This patch adds support to supermin for using a DAX root filesystem. The corresponding libguestfs patches will be posted shortly once I've tested them a bit more. This requires qemu >= 2.6. Unfortunately it's not really a win for a few reasons: - Requires enabling ACPI, which slows everything down by hundreds of

The driver was renamed from ibmvscsic to ibmvscsi on kernel 3.7.

v1 -> v2: - If we split out the init program into a separate init/ directory, that makes it much easier to build against an alternate libc. I tried to build against uClibc, but uClibc requires an entire build chain, which looked like it was going to be a massive ballache. Rich.

Allow an alternate libc, such as dietlibc, to be used for the init binary in the supermin appliance. Rich.

Document what each module does, using *.mli files. Remove the --dtb option, it's obsolete. Rename modules according to their purpose. Rich.

Hi, Rich: I met a supermin issue on CentOS 7.1: supermin: version: 5.1.10 supermin: rpm: detected RPM version 4.11 supermin: package handler: fedora/rpm supermin: acquiring lock on /root/test/aaa/lock supermin: build: /usr/lib64/guestfs/supermin.d supermin: build: visiting /usr/lib64/guestfs/supermin.d/base.tar.gz type gzip base image (tar) supermin: build: visiting

After supermin has finished running, the initramfs files sit around occupying swappable memory but serving no further purpose. This saves a little memory, at the cost of about 1ms of extra boot time. --- init/init.c | 50 ++++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 48 insertions(+), 2 deletions(-) diff --git a/init/init.c b/init/init.c index 733d66e..5ac53e9 100644 ---

Hi, to ease debugging issues with appliances (e.g. when used in libguestfs), using --include-packagelist will add a file containing the list of all the packages used.

Require the root= parameter is passed to specify which root (apppliance) to mount. Libguestfs has done this since 2012. The other two patches are small code refactorings in the init program. Rich.

We want to exclude virtio-gpu since it's irrelevant, large, and pulls in other unwanted dependencies (modeswitching, drm). Add a second list of kmods which is a blacklist, applied after the first. This reduces the libguestfs initrd size from 39M down to 17M, with concomitant small reductions in boot time. --- src/ext2_initrd.ml | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-)
