2016-11.1-x86_64 complete.
The changes are as follows. First, new/deleted files:
.gitignore
fs_skeleton/etc/SLAC_properties
fs_skeleton/etc/busybox.conf
fs_skeleton/etc/init.d/S45telnetd
The .gitignore file just has changes dealing with the fact that I use
BBEdit on the Mac to edit with and it creates meta-data files about any
of the files I've edited (to do things like retain window positions,
etc...).
The SLAC_properties, busybox.conf, and S45telnetd files were completed
during the RC1-RC3 phase but were never checked in.
The modified files are as follows:
config/bb-1.25.x.config
config/br-2016.11.1-common.config
device_table.txt
fs_skeleton/etc/group
fs_skeleton/etc/passwd
fs_skeleton/etc/shadow
scripts/save-version-info.sh
The bb-1.25.x.config file was updated by using `make
busybox-menuconfig`. The only thing that actually changed was the
setting to disable telnetd and the setting to enable SUID capability,
which we're applying to chrt. You have to copy the entire .config file
that is constructed using `make busybox-menuconfig` to the site's
bb-1.25.x.config file.
The br-2016.11.1-common.config was constructed using `make menuconfig`,
and the only thing that was done was to say that we wanted SHA-256 for
password hashing rather than MD5. That creates a .config file but you
have to compare the changes from the new .config file with the previous
.config.old file, and then just add the changes between those two to
br-2016.11.1-common.config file.
The device_table.txt file, etc/group, etc/passwd, and etc/shadow files
all came from the RC1-RC3 deployments but were never checked in.
The save-version-info.sh file has a problem where some information for
the build itself, using git to construct it, no longer works. For now,
those items were just commented out.

This allows us to run poweroff, reboot and chrt with no password
'ssh -p 8022 laci@0.0.0.0' can be used for access
fixes an issue where OpenSSH clients complain about changing host identification between reboots. By default OpenSSH (and probably other clients, too) use ecdsa as the cipher. Since we did not have an ecdsa host key, and dropbear was run with -R, dropbear would generate a new ecdsa host key that would not persist across reboots. Adding the ecdsa key avoids this issue. ed25519 is not supported by the version of dropbear here, but I added the key regardless for the next time we upgrade.

Somewhat chunky PR, changes summarized below. Nearly the same as the 2019.08 PR.
Removed Software
telnetdTelnet daemon has been removed. IT doesn't want us using telnet since it's an insecure protocol and we have ssh anyways.
New Software
sudoAdded sudo to allow for certain scripts to match between centos7-lite and this image. For example,
sudo chrtworks passwordless on both of these images./etc/sudoersis setup to give laci, flaci, acctf and spear passwordless access to chrt, poweroff, shutdown and rebootperfThis was added to allow an engineer in TID to profile an IOC. It's probably useful to have in our toolbox on buildroot.
