ldconfig

• musl does not need an ldconfig as it uses its own search mechanism
• Do not symlink to true because true is a symlink to toybox on glaucus
• Implement ldconfig as a stub instead

Implementations

• smaeul (most complete, uses scanelf, requires PAX):
  • https://github.com/smaeul/musl-utils
  • https://git.adelielinux.org/adelie/packages/-/merge_requests/57/diffs?commit_id=c631e4fc5ab64a9ad668ed5f753348ce8eae5219
• alpine (uses scanelf, requires PAX): https://github.com/libertine-linux-packages/musl_ldconfig
• libertine (identical to alpine, uses scanelf, requires PAX): https://github.com/libertine-linux-packages/musl_ldconfig
• gentoo (does not use scanelf from PAX, but has BASHisms): https://gitweb.gentoo.org/repo/gentoo.git/tree/sys-libs/musl/files/
• Debian ld-musl-config is for appending paths to /etc/ld-musl-x86_64.path and not an ldconfig replacement
• Noname uses a shebang only #!/bin/sh inside ldconfig
• scanelf is part of pax-utils on Arch
• smaeul’s ldconfig was added to Adelie because alpine’s ldconfig was limited and depended on scanelf, and smaeul’s ldconfig still does not check for scanelf, but maybe they’ll check in the future: https://git.adelielinux.org/adelie/packages/-/merge_requests/57/commits
