The branch releng/13.2 has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=ac25a113775ad527a0fc4040738bfc9e43c7db4e commit ac25a113775ad527a0fc4040738bfc9e43c7db4e Author: Mitchell Horne <mhorne@FreeBSD.org> AuthorDate: 2021-02-11 14:29:00 +0000 Commit: Mitchell Horne <mhorne@FreeBSD.org> CommitDate: 2023-02-23 18:10:19 +0000 loader: always install help files Address two issues with current help file logic: The existing condition prevents the common help file from being installed when there are no additional help files defined. This results in no loader.help on EFI platforms, for example. Second, due to the fact that we build and install multiple loader types, each successive install will clobber the previous loader.help. The result is that we could lose type-specific commands, or possibly list them in loaders that do not have such commands. Instead, give each loader type a uniquely named help file. The EFI loader will look for /boot/loader.help.efi, userboot will look for /boot/loader.help.userboot, etc. The interpreter variant has no effect on which help file is loaded. This leaves the old /boot/loader.help unused. Some credit for the final approach goes to Mathieu <sigsys@gmail.com> for their version of the fix in https://reviews.freebsd.org/D22951.
