            Bug ID: 12726
           Summary: systemctl preset-all failed for ctrl-alt-del.target
           Product: buildroot
           Version: 2020.02
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at buildroot.uclibc.org
          Reporter: melanie at trash-mail.com
                CC: buildroot at uclibc.org
  Target Milestone: ---

Created attachment 8421
  --> https://bugs.busybox.net/attachment.cgi?id=8421&action=edit
Console log output

When finalizing target directory, buildroot executes the 'systemctl preset-all'
command to preset (enable/disable) all systemd unit files.
This command runs successful during a full rebuild (after 'make clean'),
however on subsequent partial rebuild attempts it fails with exit code 1 (log
output attached).

A very similar issue was reported to the systemd-developers (ref [1]) but
closed as 'not-a-bug'.

A possible solution that works for me is to add the '--force' option to the
command.

--- Comment #1 from Yann E. MORIN <yann.morin.1998@free.fr> ---
M?lanie, All,

Sorry, I could not reproduce the failure with this defconfig, enither on
2020.02, nor on master:

    BR2_arm=y
    BR2_cortex_a7=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_INIT_SYSTEMD=y

This is during a make from scratch:
    $ make

    rm -f /home/ymorin/dev/buildroot/O/build/locales.nopurge
    [...]

Then a subsequent make would yield:
    $ make
    [...]
    /home/ymorin/dev/buildroot/O/host/bin/systemctl
--root=/home/ymorin/dev/buildroot/O/target preset-all
    rm -f /home/ymorin/dev/buildroot/O/build/locales.nopurge
    [...]

As you can see, neither the first nor the the second invocation cause any
issue.

Care to share a bit more info about your config and your host, please?

--- Comment #2 from Melanie <melanie@trash-mail.com> ---
Okay, during further troubleshooting I realized that the problem was caused by
my custom configuration, which modifies the target directory (deletes all
preset-configuration-files) after the 'finalizing target directory' phase where
the 'systemctl preset-all' command runs (this explains why a full rebuild had
succeeded but subsequent partial rebuild attempts have failed).

The fact that the 'systemctl preset-all' command fails when there are no
preset-configuration-files at all on the target file system, is a systemd
issue, so I'm closing this bug report here as invalid.
