+Subject: [PATCH] dracut-install: simplify ldd parsing logic
+
+The previous logic would not handle absolute paths on the left side of
+the "=>" properly. For example, on Gentoo ARM64, ldd outputs this:
+
+ /lib/ld-linux-aarch64.so.1 => /lib64/ld-linux-aarch64.so.1
+
+At runtime, the kernel tries to load the file from /lib, and fails if we
+only provide it in /lib64.
+
+Instead of looking for the first slash after the "=>", just look for the
+first slash, period. This would fail if we somehow had a relative path
+on the left side (foo/libbar.so), but I'm not aware of any binaries that
+would contain such an entry in DT_NEEDED.
