Description Yongcheng Yang 2021-03-30 03:14:46 UTC
Description of problem:

The service nfs-convert has been enabled by systemd preset (via Bug 1683101).
As package nfs-utils not installed by default. It will stay off even after we just installing the package (the Fedora policy - refs: https://www.freedesktop.org/wiki/Software/systemd/Preset/). But it should become enabled on the next reboot.

However I just realized that even after rebooting this nfs-convert is still in status disabled.

Executing both 'systemctl enable nfs-convert' and 'systemctl preset nfs-convert' can enable it. But why it not being enabled by default? Which is the intention of systemd preset IMHO.

This may not be a real but. But please help check where's the problem. Thanks!


Version-Release number of selected component (if applicable):
systemd-239-45.el8.x86_64
nfs-utils-2.3.3-41.el8.x86_64
redhat-release-8.4-0.5.el8.x86_64

How reproducible:
always

Steps to Reproduce:
1. yum install nfs-utils
2. reboot
3. systemctl is-enabled nfs-convert

Actual results:

No. That's not how it works. "systemctl preset" must be called explicitly, just like "systemctl enable".

... so nfs-utils rpm should be doing it.
