+1 to understanding the impact on $HOME, if any.
Will this change affect existing chroots, or only newly created ones?
Will $HOME path be changed? If so, and existing chroots will be affected, will my existing homedir contents remain present e.g. via symlink or mount or dir rename?
Will the homedir of $USER still be $HOME?
Will $LOGNAME and any other variables that usually match $USER be updated too, or remain as-is?
