removing net/samba?

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

net/samba contains version 3.x of samba, which was discontinued in 2015.

https://wiki.samba.org/index.php/Samba_Release_Planning

We have net/samba4 for a long time now (2015). samba regularly issues
new CVEs, so samba 3.x has lots of known vulnerabilities by now.

Only the following packages still depend on net/samba instead of samba4:

net/gnome-vfs-smb
sysutils/amanda-client
sysutils/backuppc
x11/kde-runtime4
x11/kde-workspace4

I suggest we switch them to samba4 and remove samba.

Any comments?
