From downstream (Fedora) bugreport - https://bugzilla.redhat.com/show_bug.cgi?id=1899412

Description of problem:

The gparted shell script uses systemctl to mask .mount units. The output of "systemctl list-units" has changed a while ago, and the script no longer understands the new output format.

The .mount units are not masked, and devices could possibly be mounted while running gparted.

Version-Release number of selected component (if applicable):

The issue has been seen also in earlier Fedora releases. When it occurred first time I don't know.

How reproducible:
Always.

Steps to Reproduce:

1. As root run gparted

Actual results:

[root@mybox ~]# gparted
Unit \xe2\x97\x8f.service does not exist, proceeding anyway.
GParted 1.1.0
configuration --enable-libparted-dmraid --enable-online-resize
libparted 3.3

The .mount units are not masked.

Expected results:

The .mount units are masked while running gparted, and unmasked when terminating gparted.

Add the "--plain" keyword and you get a listing the gparted script understands.

I don't know when systemctl got the "--plain" keyword, but it does work in Fedora33.
