The code below enables contextual alternates and ligatures but disables them on your `cursor-line` so you don't sacrifice "editability".
* {
-webkit-font-smoothing: antialiased;
-webkit-font-feature-settings: "liga" on, "calt" on;
}
atom-text-editor .cursor-line {
-webkit-font-feature-settings: "liga" off, "calt" off;
}

mutability / OVERLAYFS

readonly root via overlayfs
- install the two shellscripts into the appropriate places under /etc/initramfs-tools
- run update-initramfs
- put "overlay=yes" on the kernel command line
- reboot
With the overlay in place, the real root is mounted readonly on /ro.
Only the root fs is changed, other filesystems are mounted normally.
Remove "overlay=yes" (or change it to something other than yes) and reboot to go back to readwrite.
(This probably means that you want the commandline config to live somewhere other than on the root fs, e.g. under /boot)

Bash internal field separator (IFS) usage.

Bash internal field separator (IFS) usage

The IFS internal variable is used to determine what characters Bash defines as word/item boundaries when processing character strings. By default set to whitespace characters of space, tab, and newline.

Running the example ifs.sh, comparing the difference between the default and setting only newline as a boundary we get the following output:

/path/to/first

/path/to/second
