Subject: [Buildroot] [PATCH v4 4/4] system: Warn if systemd is used with kernel < 4.15
Date: Fri, 22 Jul 2022 12:16:51 +0200	[thread overview]
Message-ID: <20220722101653.7475-4-nolange79@gmail.com> (raw)
In-Reply-To: <20220722101653.7475-1-nolange79@gmail.com>

To quote the README:

> Kernel versions below 4.15 have significant gaps in functionality and
> are not recommended for use with this version of systemd. Taint flag
> 'old-kernel' will be set. Systemd will most likely still function, but
> upstream support and testing are limited.
