For all the details, see patch #4.

TL;DR: SIGALRM does not interrupt line reading using <>, causing the
installer to hang on country detection. Fix it by using
Proxmox::Sys::Command::run_command(), which properly interacts with

Patch #1 is a rather mundane fix for some niche cases, #2 and #3 are
simply preparatory and to not alter existing behaviour.

Christoph Heiss (4):
  low-level: initialize UI backend for 'dump-env' subcommand too
  sys: command: allow terminating the process early from log subroutine
  sys: command: add option to not print process output to stdout
  fix #4872: run env: use run_command() for country detection
