I got the error when trying to run "who" from musl compiled coreutils
package. I assume there's a good reason but I have to ask...
Why not set _PATH_UTMP to /var/run/utmp instead? Or set it at build time
based on actual utmp location?
./include/paths.h:#define _PATH_UTMP "/dev/null/utmp"
./include/utmp.h:#define _PATH_UTMP "/dev/null/utmp"

The intent was/is to avoid the creation of a utmp file since musl does
not use or support it. However the error you're reporting has been a
recurring topic so perhaps we should do something different. I'm not
sure what. From the app side, --disable-utmp might be useful if it's
available, since trying to use utmp is not going to do anything
meaningful.

That's okay. I'll just rename the "who" executable and use the rest. I
built coreutils mostly for the "sort" program. I can use the standard "who".
How about change "/dev/null/utmp" to
""/dev/null/musl_does_not_support_utmp". Same for wtmp. And add a comment
where the file is specified in the headers?
