Hello.

Everytime I try to install a package in FreeBSD 14.2-RELEASE-p1,this is
what happens :

marietto# pkg install qcad

Maybe I found the solution here :

https://lists.freebsd.org/archives/freebsd-stable/2023-February/001144.html

but I don't' understand what to do,since :

1) I don't have any /libexec/rc/rc.d/machine_id on my 14.2-RELEASE-p1

2) I don't have any /etc/rc.subr

Thanks.
