Thanks, I missed that. With virtual/crypt-native in ASSUME_PROVIDED this is consistent with how OE-core treats other host-provided libraries. I'll drop the patch. One small follow-up if it's worth the time: the failure mode for users who miss the doc update is a configure error deep in shadow-native (checking for crypt in -lcrypt... no -> configure: error: crypt() not found), which doesn't obviously point at "install libcrypt-dev on the host". Would a sanity-check addition (something along the lines of ./meta/classes-global/sanity.bbclass testing for crypt.h / -lcrypt on the build host and emitting the same hint as the docs) be welcome? Happy to put a patch together if so.
