Comment:
@ericonr til that `LOGNAME` is actually specified by POSIX, I didn't know that... still doas says it sets `LOGNAME`, period, and sudo says it does unless special precautions are taken.

If I understand correctly:
- musl is technically correct relying on LOGNAME,
- sudo & doas setting LOGNAME is technically incorrect (but probably the right choice) unless they actually login with utmp etc (doas doesn't, sudo mentions utmp/wtmp enough time that I believe they do)

so either musl resorts to strange hacks to handle the situation or until the musl guys do something like https://skarnet.org/software/utmps/ (unlikely) it looks to me like the current behavior is the least-worst option.
