While we've worked around this by setting RELEASE_UPGRADER_NO_SCREEN=1
in friendly-recovery, it'd be better to make sure that the screenrc file
is loaded by the release-upgrader all the time.
So in DistUpgrade/DistUpgradeMain.py we should change how screenrc is
loaded:
# unset escape key to avoid confusing people who are not used to
# screen. people who already run screen will not be affected by this
# unset escape key with -e, enable log with -L, set name with -S
cmd = ["screen",
"-e", "\\0\\0",
"-L",
"-c", "screenrc",
"-S", SCREENNAME]+sys.argv
logging.info("re-exec inside screen: '%s'" % cmd)
os.execv("/usr/bin/screen", cmd)
