Comment # 78 on bug 1165780 from Martin Loviska

Hello, the problem seems to persist in sle15sp2 ( tested on QR3 JeOS candidate
- sle-15-SP2-JeOS-for-kvm-and-xen-QR-x86_64-Build15.80 ).

* systemd package list:
util-linux-systemd-2.33.1-4.13.2.x86_64
libsystemd0-234-24.79.1.x86_64
systemd-presets-common-SUSE-15-8.3.1.noarch
systemd-presets-branding-SLE-15.1-20.5.1.noarch
systemd-234-24.79.1.x86_64
systemd-sysvinit-234-24.79.1.x86_64

/usr/lib/systemd/system-preset/90-default-SLE.preset still enables
btrfsmaintenance-refresh.service.
