For the record, this is a followup to Efraim=E2=80=99s proposal in . Efraim Flashner skribis: > Option 1: > Track down the ~220 crates which form the dependency graph (of crates) > for librsvg and pin them until the next core-updates cycle.

The downside is that it=E2=80= =99s a lot of crates to take care of, and we might still accidentally overlook seemingly innocuous crate upgrades that end up causing major rebuilds. > Option 2: > Use the bundled crates and treat it as just part of the librsvg source > code.=C2=B2 > > Option 2b: > Use the bundled crates for now to finish with core-updates-frozen and > revisit this immediately on core-updates (not frozen). This option will involved a rebuild on x86_64, but the advantage is that we=E2=80=99ll be safe going forward: we won=E2=80=99t accidentally cause wo= rld rebuilds just because an obscure crate somewhere has been upgraded.

Same here; it=E2=80=99s not ideal, but it seems like the most reasonable short-term option. If there are no objections, I=E2=80=99d suggest that you go ahead with this plan. Thanks for keeping the ball rolling! Ludo=E2=80=99.
