Fast data transmission via TCP over a lossy link.
Rescuing home partition from ZFS, actually that doesn't really count since I did have to reinstall (was no longer booting), but recovering the Home partition from ZFS and to the other ext4 drive was much harder than it should've been and that's why I would never recommend people use ZFS.
oh god zfs.
tell me, please, who thought it was a good idea for a filesystem to remember the last machine it was mounted from and refuse to let itself be mounted by a different operating system instance even if all the hardware is present?
agree. zfs is a hairy beast with nice features
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.
