The Fedora 34 release is planned
for April 20 — a plan that may well come to fruition, given that the
Fedora project appears to have abandoned its tradition of delayed
releases. As part of that schedule, any proposals for system-wide changes
were supposed to be posted by December 29. That has not stopped the
arrival of a
late proposal to add file signatures to Fedora’s RPM packages, though.
This proposal, meant to support the use of the integrity measurement
architecture (IMA) in Fedora, has not been met with universal acclaim.
