# In order to prevent writing as root:root in Sublime, we have to run the Sublime Text container
# as the user that creates the container. Normally we do this by passing $UID.
# But just passing $UID along isn't enough - Sublime has to be started by a user that exists.
# By default in the container, the only user that actually exists is root.
# Therefore we have to create a new user, and start Sublime as that user.
# This is not possible at build time, so the /run.sh script accepts an environment
# variable called $NEWUSER that creates a user and group named $USER.
# Additional note: Sublime puts a lot of stuff in ~/.config, which is mounted at runtime. Without this directory being mounted, settings/packages/etc won't persist.
