Bug#877989: debhelper: dh_systemd_enable installs template units under wrong name (regression since 10.8)

[Niels Thykier]

Package: debhelper
Version: 10.9
Severity: serious


Regression introduced in 3f3b3b8072155e978f885ecff80bef1672597804; fixed in
aaf90aff170e29fda86227583f6ce318dad7defd.

Observed in redis-server:
"""
$ DH_VERBOSE=1 dh_systemd_enable debian/*.service
    install -p -m0644 debian/redis-server.service 
debian/redis-server/lib/systemd/system/redis-server.service
    install -p -m0644 debian/redis-server\@.service 
debian/redis-server/lib/systemd/system/redis-server.service
"""

Note that the template @.service overwrites the original service
instead of being installed as an "@.service".

Thanks,
