This fixes
isDbusError
function, introduced by commit bacfc2c. Due to atype error it was not working at all.
This also fixes the whole "retry on dbus disconnect" logic, introduced
in PR #2923. Most probably it was not working at all before this fix.
This also fixes a regression in
startUnit
(andcgroupManager.Apply()
),which should never return "unit already exists" error but it did (#2996).
A test case is added to check that the last issue is fixed.
