From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What is the most duct-tape thing you've done to Linux? (lemm.ee)

tell me the most ass over backward shit you do to keep your system chugging?
here's mine:
sway struggles with my dual monitors, when my screen powers off and back on it causes sway to crash.
system service 'switch-to-tty1.service'

[Unit]
Description=Switch to tty1 on resume
After=suspend.target

[Service]
Type=simple
ExecStart=/usr/local/bin/switch-to-tty1.sh

[Install]
WantedBy=suspend.target

'switch-to-tty1.service' executes '/usr/local/bin/switch-to-tty1.sh' and send user to tty1

#!/bin/bash
# Switch to tty1
chvt 1

.bashrc login from tty1 then kicks user to tty2 and logs out tty1.

if [[ "$(tty)" == "/dev/tty1" ]]; then
    chvt 2
    logout
fi

also tty2 is blocked from keyboard inputs (Alt+Ctrl+F2) so its a somewhat secure lock-screen which on sway lock-screen aren't great.

Does your FS support online resizing?

Yeah. I mainly use btrfs; it supports online growing and shrinking.

Be super careful about partition sizes. [...]

I know. I have done plenty of same device partition resizing. I know the pit falls, and for safety shrink the FS to below what the LV is going to be.

Have backups.

Thanks for the reminder. I've been meaning to set up snapshot backups for this machine using rsnapshot as an experiment. I mainly use Dirvish

I use rsync with a custom shell script to manage the number of incremental copies. You'll probably prefer something less janky.

That sounds pretty much like what Dirvish and rsnapshot do. Both wrap rsync.
