Change is not always for the better. This page chronicles bull*$&! that has come down the Linux pipeline.\_Evolution\_of\_a\_Programmer.html


Predictable Network Interface Names

Someone has controversially decided that it is better for systems to have obtuse and confusing ethernet and wireless interface abbreviations such as enp0s25 instead of eth0. Remember this makes things simpler, and easier for people (but who?).

In reality, most people get the shaft, and perhaps 10% (a small proportion) of users benefit. This raises the bar for entry level people to get started. Adding unnecessary complexity to Linux.

Apt instead of Apt-get

This is a tentative, based on whether they remove support for apt-get. If that is the end goal, then this will be a valid regression, until then, they live side by side. I don't need apt, when apt-get does the job. Needless changes. There must be something more important to do than this.

Debian 10: iptables has been replaced with nftables, after nearly 20 years

"Those are some great firewall rules you've configured there. It would be a shame if someone was to make them obsolete."

It started with Ipchains in 1998. In 2000, there was the last stable release of ipchains, which means if not by then, shortly after iptables took over. It's been 19, 19 years since then. Suddenly now, a new firewall is needed. Is this necessary for most people? Doubtful. Again, a small minority will benefit. Most will get the shaft. Imagine if you couldn't buy a certain tool at the store. Say, hand saws are no longer sold. You now are forced to buy an electric jigsaw. Is this necessary? Can't we have both? Who thought changing a fundamental part of the software was a good idea? They could not had good intentions, if only for how much work they will force admins to do, with any update. Another good reason to abort Debian. Systemd is the first.

From Wikipedia

A command to drop any packets with the destination IP address

iptables was:

iptables -A OUTPUT -d -j DROP

nftables now is:

nft add rule ip filter output ip daddr drop

More complex. Fail.

With one fell swoop, thousands of iptables scripts and knowledge were made useless. Imagine if you were no longer allowed to play baseball. Now instead, you had to learn baseketball.

ifconfig replaced with ip

ifconfig, is simpler to use, and easier to view for basic nic information, or setting an ip (ifconfig eth# netmask ip is unnecessary complexity for most use cases. This raises the bar for entry level people to get started. Adding unnecessary complexity to Linux.

ifconfig remains in /sbin/ifconfig, and requires root but the effort has been made to obsolete it. Don't change, what doesn't need to change.

/etc/resolv.conf depreciated

All you should need for DNS is a one line text file that points to a DNS server. Put that in /etc/resolv.conf. The simplicity of that is a threat to more obtuse OS, therefore there will be an effort to complicate it. This raises the bar for entry level people to get started. Adding unnecessary complexity to Linux.

Aptitude Descriptions

debian 8:

Automatically installed: no
Version: 1.0.2k-1~bpo8+1
Priority: optional
Section: utils
Maintainer: Debian OpenSSL Team <>
Architecture: amd64
Uncompressed Size: 1,090 k
Depends: libc6 (>= 2.15), libssl1.0.0 (>= 1.0.2~beta3)
Suggests: ca-certificates
Description: Secure Sockets Layer toolkit - cryptographic utility
 This package is part of the OpenSSL project's implementation of the SSL and TLS cryptographic protocols for
 secure communication over the Internet.

 It contains the general-purpose command line binary /usr/bin/openssl, useful for cryptographic operations such
 * creating RSA, DH, and DSA key parameters;
 * creating X.509 certificates, CSRs, and CRLs;
 * calculating message digests;
 * encrypting and decrypting with ciphers;
 * testing SSL/TLS clients and servers;
 * handling S/MIME signed or encrypted mail.

Dropping Support for i386

Some distributions are dropping intel 32-bit support. With one fell swoop, hundreds of thousands of laptops and desktops made before 2006 and 2007 lost the ability to use modern OS. EDIT: this was taken back, temporarily. It stands, that some OS must support 32 bit i386, otherwise a lot of devices will be headed to landfills.

Setting up Networking has become more complicated

What was (/etc/networking/interfaces):

auto eth0
iface eth0 inet static

Example taken direct from For DNS, a one liner in /etc/resolv.conf will suffice.

Now is (w/

  version: 2
  renderer: networkd
          search: [mydomain, otherdomain]
          addresses: [,]

Example direct from

GNU\Linux has and is being obfuscated.

SystemD FAIL

A plot to make linux worse, which was brought into all the major distributions through the back door. It deserves its own section.

Reboot FAIL

A demonstration of Ubuntu and Systemd being unable to reboot the computer within a reasonable amount of time. It takes 5-10 minutes for reboot to occur. Keep in mind, that this init has been on this distribution for years now (from 16.04, so 2016-2020). Sysvinit does not have this problem, and reboots within 10-20 seconds. Note that this is a remote ssh session.

In Ubuntu 19.04, reboot can take upwards of 5-10 minutes to actually reboot the computer. Note that this occurs in only SystemD based distributions. A similar Debian (9 or 10) w/sysvinit reboots within 10-15 seconds.

I thought I would test systemd, so I installed Zoneminder on Ubuntu 19.04, and it demonstrates this problem. After witnessing the lifeforce of my computer being ripped out by this init, I threw the towel in and installed Devuan.

For the record, I also noticed the system to run noticeably slower. CCTV is a good benchmark for a server, as it involves a lot of CPU usage, unlike many file servers, or db servers.

Example Error when Trying to Reboot

user@host:~$ systemctl reboot
Error getting authority: Error initializing authority: Error sending credentials: Error sending message: Broken pipe (g-io-error-quark, 44)
Failed to set wall message, ignoring: Failed to activate service 'org.freedesktop.login1': timed out (service_start_timeout=25000ms)
Failed to reboot system via logind: Connection timed out
Failed to start Connection timed out
See system logs and 'systemctl status' for details.
It is possible to perform action directly, see discussion of --force --force in man:systemctl(1).

And it will now take my machine 5-10 minutes to reboot.

Udev requires reboots after Ubuntu 14

When I started using Linux distributions one of the things I noticed was how well updates were handled, compared to proprietary software. No forced reboots, no update screens that leave the user waiting. You can use your computer while it's updating. This statement ("Linux never needs to reboot when it updates") changed with udev requiring a reboot in Debian 8 or 9 occasionally (However, it's still extremely rare).

Device Tree Bindings

ARM. Sounds like a good idea, except you need a different ISO for each single ARM CPU. Unlike the intel i386 which you can use one single ISO for ANY desktop/laptop.

ARM is fail. DTB is busy work, and fail.

This is one reason why Android is a failure.

It looks like unfortunately that RISCV will also follow this path.


Many embedded systems use less fancy buses that don't support enumeration. This was true on PC up to the mid-1990s, before PCI overtook ISA. Most ARM systems, in particular, have buses that don't support enumeration. This is also the case with some embedded x86 systems that don't follow the PC architecture. Without enumeration, the operating system has to be told what devices are present and how to access them. The device tree is a standard format to represent this information.

The main reason PC buses support discovery is that they're designed to allow a modular architecture where devices can be added and removed, e.g. adding an extension card into a PC or connecting a cable on an external port. Embedded systems typically have a fixed set of devices¹, and an operating system that's pre-loaded by the manufacturer and doesn't get replaced, so enumeration is not necessary.

Well guess what - It's necessary now.
