3	# The distinction that matters is packages versus requested-packages, and
4	# base-local-replacements versus requested-base-local-replacements. A request
5	# that never becomes active is recorded in the second of each pair and absent
6	# from the first, and it survives a reboot looking exactly like a request that
7	# worked. Reading the human `rpm-ostree status` output instead is how a no-op
8	# gets mistaken for an applied hotfix.

12	# With --requested PREFIX it prints nothing but the requested-packages of the
13	# booted deployment whose name starts with PREFIX, one per line, for a caller
14	# that means to uninstall them. The exact strings matter: a request is recorded
15	# under whatever was typed to install it, so a package installed by full NEVRA
16	# cannot be removed by its bare name — `rpm-ostree uninstall alloy-demo` on a
17	# machine holding `alloy-demo-0.0.2-1.fc43.x86_64` answers "not currently
18	# requested" and leaves it in place. Measured 2026-08-14, and it is the whole
19	# reason this mode exists rather than the caller writing a package name.
