Configure proper line wrapping for lish
I have a few usability problems with lish.
Line wrapping is nonexistent, making it difficult to perform
maintenance tasks that require the use of lish. For example, trouble-
shooting SELinux policy modules - this isn't something I can simply say "okay I'll just use ssh" when I can't login remotely due to SElinux
policies.This feels related but may not be - I notice that I am within a screen session that uses ^A as the control escape but does not allow
me to change the the escape. ^A is the beginning of line escape, and it's often followed by ^K which has the fun effect of killing the screen.
As a result of these two coinciding factory, the lish console is nearly unusable for me. This happens regardless of how I attempt to access the lish console.
Are there solutions for these usability issueS?

Hello,

Thank you for this feedback. This is definitely a great observation regarding the Lish console, and I can understand why it would be frustrating. I will pass along this suggestion to our development team, regarding line wrapping.

Can you give more details about this? What screen session are you in? Are you saying that normally you would use ^A to escape that screen session, but in the Lish console it's not working for you? I'm a little confused about what you are asking here, so any additional details would be helpful!
Thanks,

It's a virtualized console with no actual terminal to inherit size from, so it defaults to the standard cols and rows. I believe you can influence the size using:
stty cols "$cols" rows "$rows"
Since it runs in screen, control-a is intercepted by the screen session. You can get screen to pass down a control-a with the following sequence:
control-a followed by a.
However, these escape sequences aren't changeable.
Hope that helps,
