>Description:
Currently the .so symlinks are shipped in the `base' set, not the `comp' set.  For example:

    450 ./usr/lib/libmagic.so				base-sys-shlib		compatfile
    451 ./usr/lib/libmagic.so.8				base-sys-shlib		compatfile
    452 ./usr/lib/libmagic.so.8.0			base-sys-shlib		compatfile

https://nxr.netbsd.org/xref/src/distrib/sets/lists/base/shl.mi?r=1.998#450

Of course the .so.N symlink and the .so.N.M file need to be in base, because the run-time loader ld.elf_so / rtld look for those to load at run-time when running programs.

But the .so symlink is only used by the build-time linker, just like any corresponding .h files which are already in comp, not base.  So there's no meaningful way to use the .so symlink from base anyway.
>How-To-Repeat:
code inspection
>Fix:
Yes, please!

Need to carefully consider -- and document somewhere -- the potential fallout arising from moving files from one set to another.
