Installing the less package into the image will solve this problem. As journal is a key functionality of systemd, I think we'd better add the 'less' package to the RDEPENDS of systemd. //Chen Qi 40273 2 richard.purdie 2014-02-10 12:53:02 +0000 Adding less as a dependency of systemd is a bit of a hack. I believe busybox implemented some better handling of this? I'd really prefer to see: a) busybox handling of the escape sequences handled (backport the patch?) and/or b) systemd learning not to use the sequences on things that aren't terminals 46911 3 Qi.Chen 2014-11-11 02:05:20 +0000 It's not a big problem. '--no-pager' can almost always work.
