Subject: [PATCH] Install: correctly report symlink creations
803fb7
803fb7
All callers of create_symlink(), such as install_info_symlink_wants(), expect
803fb7
that to return > 0 if it actually did something, and then return that number.
803fb7
unit_file_enable() uses that to determine if any action was done
803fb7
(carries_install_info != 0) and if not, show a "The unit files have no
803fb7
[Install] section" warning.
803fb7
803fb7
Return 1 instead of 0 in the two code paths of create_symlink() when the link
803fb7
was created or replaced with a new value.
803fb7
803fb7
This fixes getting a bogus "No [Install] section" warning when enabling a unit
803fb7
with full path, like "systemctl enable /some/path/myunit.service".
803fb7
803fb7
(cherry picked from commit 3de1521427dee61000c1c124a521182b301a50de)
803fb7
Resolves: #1435098
