### Actual behaviour
Without specifying on Musl
$ last -n 20
last: cannot open /dev/null/wtmp: Not a directory
### Steps to reproduce
From cli: last
It seems the location is set to /dev/null/wtmp for some reason in a musl specific WLOC define; this was collateral damage.

Comment:
You may want to package https://skarnet.org/software/utmps/ for musl to support utmp and wtmp, I don't know if it works.

Comment:
Closing because this is expected behavior for a tool that attempts to read login databases that musl expressly declines to write.
