[Buildroot] [PATCH 1/1] fs/common.mk: move BR2_ROOTFS_POST_FAKEROOT_SCRIPT after pre cmd hooks

[Yann E. MORIN <yann.morin.1998@free.fr>]

Charles, All,

On 2020-09-10 17:30 -0700, Charles Hardin spake thusly:
> From: Charles Hardin <ckhardin@gmail.com>
> 
> The fakeroot script does not appear to be used in any of the checked
> in defconfig targets, but it seems that most often the post
> fakeroot script should be done after all the packages rules have
> been applied instead of before.
> 
> Given that a change in systemd moved the SYSTEMD_PRESET_ALL hook to
> a ROOTFS_PRE_CMD_HOOKS, there was no way to use a FAKEROOT script
> to disable a service or fixup a systemd configuration. The systemd
> move makes sense, and this just tries to preserve the same ability
> to fixup a rootfs after all the cmd hooks are processed.
> 
> Refer to commit 65b63785a642bbc565924edf365b5d7c080f961c for
> the change that instigated this reordering.

Did you verify that our run-time testing still works:

    support/testing/tests/core/test_post_scripts.py

which can be tested with:

    ./support/testing/run-tests \
        -o /path/to/where/you/want/temp/stuff \
        -d /path/to/BR2_DL_DIR \
        -k \
        tests.core.test_post_scripts

Otherwise, this change does make sense, because we do want to allow
users to be able to override the internal decisions.

Regards,
Yann E. MORIN.
