[Buildroot] [PATCH 2/2] support/testing: test_systemd.py: add linux fragment to enable CONFIG_BINFMT_MISC

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

Applied to master, thanks.

I just moved the kernel fragment with the others in the conf/ sub-dir of
the test infra. Yeah, the lxc fragment is not there, though, but that's
the outlier now.

Regards,
Yann E. MORIN.

> CONFIG_BINFMT_MISC needed by "proc-sys-fs-binfmt_misc.mount" service.

> It's because the kernel support autofs4 but not MISC binaries.
