RHEL/CentOS 7 uses SystemD predictable network interface names. This post shows you how to rename a network interfcae to eth0,/em>without modifying the kernel commnad line or any udev rules, and without requiring a sytem reboot.

Finally people are beginning to wake up and understand that systemd and Lennart Poettering, who works for Red Hat, is a cancer that will destroy and splinter the Linux ecosystem. According to a new movement, boycottsystemd.org: It represents a monumental increase in complexity, an abhorrent and violent slap in the face to the Unix philosophy, and its inherent domineering and viral nature turns it into something akin to a “second kernel” that is spreading all across the Linux ecosystem. I could not agree more. systemd flies in the face of the Unix philosophy: “do one thing and do it well,” Recently I updated my Fedora 19 system and all appeared to be well until I wanted to quickly scan in a document to send to a colleague. The scanner I used is my old trustly Canon LiDE 30. Simple-scan refused to work because it claimed that no scanners were detected. Using lsusb, I quickly determined that the scanner was detected: # lsusb Bus 002 Device 004: ID 045e:076c Microsoft Corp. Comfort Mouse 4500 Bus 002 Device 003: ID 045e:0734 Microsoft Corp. Wireless Optical Desktop 700 Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 002 Device Recently I installed Fedora 15 on a standalone system to do some testing. This system has ASUS motherboard with a single integrated Atheros 8131 Gigabit Ethernet NIC. Here is the relevant output from ipconfig -a: p33p1 Link encap:Ethernet HWaddr E0:CB:4E:1A:F6:D5 inet addr:192.168.0.114 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::e2cb:4eff:fe1a:f6d5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:62680 errors:0 dropped:0 overruns:0 frame:0 TX packets:37533 errors:0 dropped:0 overruns:0 carrier:1 collisions:0 txqueuelen:1000 RX bytes:94004479 (89.6 MiB) TX bytes:2446588 (2.3 MiB) Interrupt:44 I expected to see eth0; instead the NIC was named p33p1. The lsmod utility showed that the correct kernel module, i.e. atl1c.ko, was Udisks and udev are related. Normally, as you can see from the above examples, when a new USB stick or DVD inserted, it is automatically mounted and the file manager is displayed. Suppose, instead, that you want that USB stick or DVD to be ignored and not mounted. How would you configure your system to do this? While researching how to disable the automatic mounting of devices for a Linux kiosk project I was working on, I spent a number of hours on the Internet reading purported solutions to the problem. The majority of the solutions (probably 99%) simply did |
