Legacy resin startup script

Product support
1

Hi there. This is a fairly specific question related to a startup script we run on our machines. I’ve listed it below. It was developed with the help of resin staff a few years ago and was meant to overcome some issues we were seeing at the time. I suspect it is no longer needed but I wanted to see if anyone on your end could take a peek and verify that it is not needed.

Thanks!

#!/bin/bash

mkdir -p /tmp
mount -t devtmpfs none /tmp
mkdir -p /tmp/shm
mount --move /dev/shm /tmp/shm
mkdir -p /tmp/mqueue
mount --move /dev/mqueue /tmp/mqueue
mkdir -p /tmp/pts
mount --move /dev/pts /tmp/pts
touch /tmp/console
mount --move /dev/console /tmp/console
umount /dev || true
mount --move /tmp /dev

mount -t tmpfs dbus /run/dbus

# Since the devpts is mounted with -o newinstance by Docker, we need to make
# /dev/ptmx point to its ptmx.
# ref: https://www.kernel.org/doc/Documentation/filesystems/devpts.txt
ln -sf /dev/pts/ptmx /dev/ptmx

mount -t debugfs nodev /sys/kernel/debug

:speech_balloon:Hello Areth
Do you remember which issues this script was meant to overcome?
Do you have a link to a discussion that led to the creation of this script?
Where do you run it?

Most probably, the changes made by this script are required by your app.

I’m working on digging that information up. I was hoping it might be obvious from the script what was going on. I’ll seee what I can figure out and re-post here if you are interested. Thanks!
