The variable is renamed to SYSTEMD_PAGERSECURE (because it's not just about less now), and we automatically enable secure mode in certain cases, but not otherwise. This approach is more nuanced, but should provide a better experience for users: - Previusly we would set LESSSECURE=1 and trust the pager to make use of it. But this has an effect only on less. We need to not start pagers which are insecure when in secure mode. In particular more is like that and is a very popular pager. - We don't enable secure mode always, which means that those other pagers can reasonably used. - We do the right thing by default, but the user has ultimate control by setting SYSTEMD_PAGERSECURE. Fixes #5666. v2: - also check $PKEXEC_UID v3: - use 'sd_pid_get_owner_uid() != geteuid()' as the condition
