The problem with the awkward line wrapping is still present. Sometimes it doesn't come up until I change the size of terminal window. Is that on the master branch? More interesting is that if I run `busybox sh` the issue is not present and the line wraps correctly. The issue happens with ssh as well as serial. Interesting. I tried to install the `xterm` pkg which has `resize` binary for changing the terminal window size, but without any luck. Why not? I know that the meta-overc devs added xterm to get resize: https://github.com/OverC/meta-overc/commit/729f50aef024db293986ff320713ddf46bcb300b Kind regards Petr Thanks for simplifying and testing again.

Re: [yocto] Awkward line wrapping in bash
Hi, Is your problem of line wrapping only on the serial console, or also on an ssh session? Which version of Yocto do you use? systemd or sys-v?

The line keeps wrapping on the first line.
