Don't be lazy and find that out yourself. Google (or your search

The systemd-devel mailing list does not develop dockerd or provide
support for it.

This also needs a man page update.

Config keys are generally capitalized. But they should be named in a
way that indicates what they're actually configuring.

Below is a proposal for adding a couple of settings to the systemd pstore

Subject: [RFC] pstore: options to enable kernel writing into the pstore

The systemd pstore service archives the contents of /sys/fs/pstore
upon boot so that there is room for a subsequent dump. The pstore is
usually backed by flash memory typically in the vicinity of 64KB.  The
pstore can contain post-mortem debug information even if kdump fails
or is not enabld.

The issue is that while the service is present, the kernel still needs
to be configured to write data into the pstore. It has two parameters,
crash_kexec_post_notifiers and printk.always_kmsg_dump, that control
writes into pstore.

The crash_kexec_post_notifiers parameter enables the kernel to write
dmesg (including stack trace) into pstore upon a panic, and
printk.always_kmsg_dump parameter enables the kernel to write dmesg upon
a shutdown (shutdown, reboot, halt).

As it stands today, these parameters are not managed/manipulated by the
systemd pstore service, and are solely reliant upon the user [to have
the foresight] to set them on the kernel command line at boot, or post
boot via sysfs. Furthermore, the user would need to set these parameters
in a persistent fashion so that that they are enabled on subsequent
reboots.

This patch allows the user to set these parameters via the systemd
pstore service, and forget about it. This patch introduces two new
settings in the pstore.conf, 'kmsg' and 'crash'. If either of these
is set to true, then the corresponding parameter is enabled in the
kernel. If the setting is false, then the parameter is not touched,
thus preserving whatever behavior the user may have previously
chosen.

[systemd-devel] dockerd broken docker works without It own docker image but need

[Dorian ROSSE]

Hello,


dockerd is broken,

docker works without It own docker image but I need,

when I run 'docker network list' It shows docker image but nothing in the 
docker container fedora window...

I have run this :

'grubby --update-kernel=ALL --args="systemd.unified_cgroup_hierarchy=0'

then I have reboot since this command line and the reboot dockerd is broken 
this next command line show the docker status :

'dockerd -D -p /var/run/docker.pid'

I happen error :

pid file found ensure docker is not running or delete /var/run/docker.pid


Thank you in advance to help myself run docker image,

Regards.


Dorian ROSSE.
