similar to: [klibc:master] run-init: Add dry-run mode

initramfs-tools wants to validate the real init program before running it, as there is no way out once it has exec'd run-init. This is complicated by the increasing use of symlinks for /sbin/init and for /sbin itself. We can't simply resolve them with 'readlink -f' because any absolute symlinks will be resolved using the wrong root. Add a dry-run mode (-n option) to run-init

systemd supports switching back to the initramfs during shutdown in order to make it easier to clean up the root file system. This is desirable in order to allow us to remove keys from RAM before rebooting, making it harder to obtain confidential information by rebooting into an environment that scrapes RAM contents.

Building on the work in ff0a614bd724f6c4c6a5014a9955dc1bc028f336, this moves the capability code down into the run-init library, so that run-init can use it as well, via the new "-d" flag.

On a train ride to Bruxelles, brought out my axe and directly attacked run_init(8). run_init(8) is dead, long live switch_root(8). The next run on switch_root(8) involves fdopendir, so another push for the upcoming stdio 1.6 branch. The following is boot tested with initramfs-tools, kinit(8) tests would very much be appreciated!? Michal Suchanek (1): [klibc] switch_root: Fix single file

This patchset applies to klibc mainline. As is it will probably collide with Maximilian's recent patch to rename run-init to switch_root posted last week. To boot an untrusted environment with certain capabilities locked out, we'd like to be able to drop the capabilities up front from early userspace, before we actually transition onto the root volume. This patchset implements this by

hello, Preparing my first klibc maintainenace release. :) My plan is to have the patches cook in klibc-queue and once everythings is fine deploy them in the main klibc repo. Please test/review belows patches. I plan to release the current queue really soon for klibc 1.5.20 due to the urgent ipconfig fixes. For now you find my patch queue on:

Hello, I was using a bunch of cpios in initramfs as a working system, and wondering why the unused files weren't being paged out to swap. So I reread ramfs-rootfs-initramfs.txt and now I know. So I wrote the attached utility. It creates a tmpfs, moves all files on the initramfs, moves / and executes the real init. It works, even with hardlinks, but it isn't the correct approach. Have

Hi, Here's a try at writing an initramfs HOWTO. This is basically a write-up of a number of interesting emails I collected over time. It could probably use an editor, more fact-checking and a bunch of other good things, but it should be better than nothing ;-) Daniel -------------- next part -------------- INITRAMFS HOWTO 0) What are klibc and initramfs?

The generator can skip a directory's contents altogether due to --ignore-non-existing, a daemon exclude, or a mkdir failure. On a --dry-run, the generator can also note the missingness of a directory while still scanning its contents. These two scenarios were conflated using a single set of missing_below/missing_dir variables in combination with transient increments in dry_run; this caused

Hi I had some doubts regarding what all the init application should do: >> so, that should that application do? >> - mount /dev/hda1 /new-root >> - cd /new-root >> - run-init 1. Of what I understand, before exitting, init should mount the realroot and execute the init process. Is realroot the '/' or the empty directory created (in the cpio archive) ?

In case anyone else is trying to make this work, here is what I did (Before 0.7.4 I had patched the regex in zentest redgreen, but that is not used any more) To use directly, it is very simple. In rspec_autotest/lib/ rspec_autotest.rb, add a -c to the spec_command in the initializer function: @spec_command = "spec -c --diff unified" This won''t help however if you want

In the past there have been discussions about adding a switch to rsync to preserve the atime on files being copied by rsync. I needed this function for a project I'm working on and decided to invent it. I've attached the diffs. Note that this has the limitations describe in previous emails, namely that preserving atime causes ctime to not be preserved. *** Patch follows *** ***
