# Fix blank PVE noVNC console on distros with util-linux >= 2.40.3:
# newer agetty sends ESC[6n (cursor position query); the VNC terminal responds
# with ESC[row;colR which agetty reads as input, clears the screen and hides
# the MOTD/banner. Setting TERM=linux in the getty unit prevents the query.
# In LXC the noVNC console is served by console-getty.service (not getty@tty1).
# /etc/environment is also written so PAM passes TERM to the login shell before
# /etc/profile runs (fixes openSUSE tset "unknown terminal type" prompt).
# Fix blank PVE noVNC console on distros with util-linux >= 2.40.3 and
# bash/readline 8.2+ (Fedora 43, Arch rolling): agetty and readline both send
# ESC[6n (cursor position query); the VNC terminal responds with ESC[row;colR
# which gets read as keyboard input (shows as "R;80R;" garbage at the prompt).
# Three-layer fix:
# 1. console-getty drop-in: TERM=linux stops agetty from querying (fixes MOTD blank)
# 2. /etc/environment: PAM passes TERM before /etc/profile runs (fixes openSUSE tset)
# 3. /etc/profile.d/99-pve-console-term.sh: re-asserts TERM=linux AFTER all other
# profile.d scripts, so readline never thinks CPR is supported (fixes R;80R garbage)
