"""Lists the package-history ledger at /var/lib/dnf_package_store/history.db
|
||
|
|
(see `pkg-apply`, which writes it as root on every install/uninstall this
|
||
|
|
app performs). The chain starts at a "baseline" node (zero mods, stock OS)
|
||
|
|
and each later node names the action, package and user that applied it.
|
||
|
|
|
||
|

Read-only, no root needed — the db directory/file are world-readable, same
|
||
|
|
convention as /var/lib/rpm-ostree.
