(cherry picked from commit 508f1ee87e816bf6b6fc8e629ccbb2d61a971169)

We set it on the kernel command line, then get it out from
there when the rescue appliance boots.
|

|

Change the appliance so PATH includes common directories. Thus
we don't need to hard-code paths to binaries (eg. "/sbin/fdisk")
everywhere.

Hi,
attached patch should make:
http://git.debian.org/?p=pkg-libvirt/libguestfs.git;a=blob;f=debian/patches/0003-appliance-Use-service-udev-start-instead-of-running-.patch;h=c9e6b8489807d4fb1247cb6a8b6f9799bad2a09e;hb=d3a21b5b6850fc3c6e7903d0f5cafa3eb4197d49
http://git.debian.org/?p=pkg-libvirt/libguestfs.git;a=blob;f=debian/patches/0004-Ubuntu-Prefer-starting-udev-by-hand-instead-of-using.patch;h=64b65a971b186e6ab1c9351e94b46d6f5aa242e0;hb=d3a21b5b6850fc3c6e7903d0f5cafa3eb4197d49
superflous. If there's an init script it uses 'service' or falls back to
calling the init script directly if it isn't there, otherwise it starts
udev directly. Tested on Debian only so far. The patch is based on
Rich's above two patches.
Cheers,

Subject: [PATCH] Check for service and use it if it's there
Based on Richard's two patches for the Ubuntu build.

Print the uptime just before the init script runs the daemon, so we
have a good idea of how long the kernel boot + init script takes to run.
|
|
|
|
|
|
|
| |
If start_udev fails for any reason, notice and fall through to manual /dev
creation.

This command runs a "rescue appliance" against a virtual machine
or disk image. This is useful for making ad-hoc interactive
changes to virtual machines.
$ virt-rescue --ro /dev/vg_trick/F11x64
Welcome to virt-rescue, the libguestfs rescue shell.
Note: The contents of / are the rescue appliance.
You have to mount the guest's partitions under /sysroot
before you will be able to examine them.
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell

The appliance shouldn't run the daemon after we leave the
rescue shell. It should just exit instead.
|
|
|
|
|
|
| |
If selinux=1 on the Linux kernel command line, then we mount
/selinux in the appliance. We will also bind-mount this
directory into guests when we run commands.

Output more debugging information from this script, to enhance the
usefulness of LIBGUESTFS_DEBUG output.
