Comment 4 Branislav Blaškovič 2016-11-09 08:49:48 EST

I've tested this with systemd-219-30.el7 in chroot:

# systemctl list-units
Running in chroot, ignoring request.

With the newest version systemd-219-30.el7_3.6 it works the same:
# systemctl list-units
Running in chroot, ignoring request.

But when used with SYSTEMD_IGNORE_CHROOT set to something bigger than 0, it actually works:
# PAGER= SYSTEMD_IGNORE_CHROOT=1 systemctl list-units
