1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack members of the community for any reason.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
  • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
  • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.

    Fast data transmission via TCP over a lossy link.

    I feel seen here, I was building a Ubuntu server and messed up the firewall settings not being able to get an internet connection, hours of trying to get back to where I was I gave up and plan to just start from scratch next time.

    Is there a way of taking system snapshots with Linux?

    Hmm I have come up with a bunch of neat solutions over the years. Where to start?

    One time I broke the sudoers file on a distro without a root account, thoroughly locking myself out. I used docker -v /:/chroot to get myself root access to my root filesystem where I fixed the sudoers file. Protip always use visudo

    I managed a CentOS system where someone accidentally deleted everything from /usr, so no lib64, and no bin. I didn't have a way to get proper files at the time, so I hooked the drive up to my Arch system, made sure glibc matched, and copied yum and other tools from Arch.

    Booted the system, reinstalled a whole lot of yum packages, and... the thing still worked.

    That's almost equivalent to a reinstall, though. As a broke college student, I had a laptop with a loose drive, that would fall out very easily. I set it up to load a few crucial things into a ramdisk at boot, so that I could browse the web and take notes even if the drive was disconnected, and it would still load images and things. I could pull the cover off and push the drive back in place to save files, but doing that every time I had class got really tiring, so I wanted it to run a little like a live system.

    I have taken a drive with filesystem issues, mounted on a different machine and either backup data I wanted to keep or copy files to make the original machine runnable.
