# Okay, so some hackery that you'll see soon needs to be explained a bit:
# These Swift binaries want libncurses.so.6 and family, but Arch provides them under
# libncursesw.so. An original copy of this package just symlinked the names, but then
# ldconfig picked them up, which lead to the wrong paths being placed into the initramfs...
# leaving an unbootable system.
# Ideally we'd be able to use patchelf --replace-needed, but that's not possible due to a glibc
# bug that cuases ldconfig to misread the SONAME and generate screwy symlinks:
# https://sourceware.org/bugzilla/show_bug.cgi?id=24294
# Therefore, instead we need to follow this process:
# - Replace /usr/lib/swift/linux from ld.so.conf.d with /usr/lib/swift/linux/export.
# - Symlink all the libraries in /usr/lib/swift/linux to /usr/lib/swift/linux/export.
# - Create the .so.6 symlinks in /usr/lib/swift/linux.
# Merge ld.so.conf.d files from the two packages
