From 52202bfc705e433a170e78529558556b0976ae71 Mon Sep 17 00:00:00 2001 From: Helmut Grohne Date: Fri, 13 Jan 2023 07:04:28 +0100 Subject: automatically set up agetty TERM when possible * debvm-create will now parse a new kernel cmdline debvm.term and if present will pass its value to agetty as TERM. * debvm-run will now detect whether it is running in a terminal in non-graphic mode and pass its environment TERM variable as debvm.term to the kernel cmdline thus closing the loop. --- share/customize-autologin.sh | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'share') diff --git a/share/customize-autologin.sh b/share/customize-autologin.sh index 5592a03..d7df555 100755 --- a/share/customize-autologin.sh +++ b/share/customize-autologin.sh @@ -3,7 +3,8 @@ # SPDX-License-Identifier: MIT # # This is a mmdebstrap customize hook that configures automatic root login on a -# serial console. +# serial console.
