CLEANUP-SYSTEM-DEFINITION-SEARCH-FUNCTIONS attempts to remove SYSDEF-PRELOADED-SYSTEM-SEARCH from the hooks, but it is never added. and right under it, SEARCH-FOR-SYSTEM-DEFINITION also assumes that it's supposed to be called explicitly after the hooks.
i'm afraid i sent this mail too early. the comment above it says: "Remove known-incompatible sysdef functions from old versions of asdf." so, if this is indeed a cleanup needed for a proper upgrade, then please ignore my mail and sorry for the noise. -- • attila lendvai • PGP: 963F 5D5F 45C7 DFCD 0A39 -- “Justice is not concerned with the results of the various transactions, but only with whether the transactions themselves are fair.” — F.A.
