Although I understand the words you=E2=80=99ve written, that doesn=E2=80=99= t match up with the reality of my actual server management or of how pkgn= g is designed: =3D=3D=3D Reality =46or real servers, you may need to patch PHP for a security issue but no= t want to upgrade java. That=E2=80=99s just the reality of server managem= ent. I might want to upgrade vim but not apache24. =3D=3D=3D pkgng Thankfully pkg already has a feature for that.=C2=A0 =C2=A0 =C2=A0pkg upgrade vim That=E2=80=99s a real thing which you are now telling me is catastrophica= lly =5B1=5D broken and should not be used. Even worse, there is a feature =C2=A0 =C2=A0pkg upgrade -g php71-* which is broken twice over. =46irst you are telling me it should never be= used. Secondly, it doesn=E2=80=99t behave the way it is documented since= it installs ALL php71 packages even if you hadn=E2=80=99t previously ins= talled them. So it ignores the =E2=80=9Cupgrade=E2=80=9D command and inst= ead behaves like =E2=80=9Cinstall=E2=80=9D. =3D=3D=3D What should happen pkg already is able to consider all the packages I=E2=80=99ve installed. = It has a database in which that list is stored and it should understand d= ependencies. In fact it does that just fine. When I run =C2=A0 =C2=A0pkg upgrade vim it detects that a dependency also needs upgrading and sorts that out for = me. Lovely. Thanks pkg. If =22pkg upgrade -g=E2=80=9D worked as documented, then we=E2=80=99d als= o be happy. That=E2=80=99s identical to =22pkg upgrade php71 php71-sessio= n php71-mysqli php71-ctype=E2=80=9D, just a convenient way to not have to= type what might be 20 packages. So Matthew, I=E2=80=99m not having a go at you (and I=E2=80=99m thankful = for the work you do), but to say I=E2=80=99m doing it wrong is perhaps mi= ssing the point. pkgng has a bug and I=E2=80=99m looking for workarounds.= If I cannot patch security vulnerabilities in PHP without restarting all= my java applications, then security issues will not be patches as often.= And that=E2=80=99s bad. I like that pkg=E2=80=99s entire reason for existing is to work out depen= dencies, but if you are saying I=E2=80=99m not allowed to use pkg for tha= t purpose and I=E2=80=99m only supposed to upgrade everything to the late= st version of everything, then there is a problem. Please cc me, since I=E2=80=99m not on the list.
