Description of problem:

vsftpd-3.0.2-4.fc20 package scriplets look like this:


postinstall scriptlet (using /bin/sh):
%systemd_post vsftpd.service
preuninstall scriptlet (using /bin/sh):
%systemd_preun vsftpd.service
postuninstall scriptlet (using /bin/sh):
%systemd_postun_with_restart vsftpd.service

Not very surprisingly this results in the following:

/var/tmp/rpm-tmp.zfGqRn: line 1: fg: no job control
warning: %post(vsftpd-3.0.2-4.fc20.x86_64) scriptlet failed, exit status 1

Moreover, since postuninstall scriptlet is affected as well, on the next update it will fail and one will end up with duplicates as 
vsftpd-3.0.2-4.fc20 will be not removed (and apparently there is no other way to remove such duplicate as with 'rpm -e --no-scripts ...).

Version-Release number of selected component (if applicable):
vsftpd-3.0.2-4.fc20
