If verifying the integrity of group files and/or password files fails, I
wouldn't call it an install "without problems".
[rocketmouse@archlinux ~]$ grep '#' -A1 /usr/lib/systemd/system/shadow.service
# Always run both checks, but fail the service if either fails
ExecStart=/bin/sh -c '/usr/bin/pwck -r || r=1; /usr/bin/grpck -r && exit $r'
[rocketmouse@archlinux ~]$ apropos pwck
pwck (8) - verify integrity of password files
[rocketmouse@archlinux ~]$ pwck --help | grep read-only -A1
-r, --read-only display errors and warnings
but do not change files
[rocketmouse@archlinux ~]$ apropos grpck
grpck (8) - verify integrity of group files
[rocketmouse@archlinux ~]$ grpck --help | grep read-only -A1
-r, --read-only display errors and warnings
but do not change files

See above.
