## Setup GOSU to match user and group ids
##
## User: user
## Pass: 123
##
## Note that this setup also relies on entrypoint.sh
## Set LOCAL_USER_ID as an ENV variable at launch or the default uid 9001 will be used
## Set LOCAL_GROUP_ID as an ENV variable at launch or the default uid 250 will be used
## (e.g. docker run -e LOCAL_USER_ID=151149 ....)
##
## Initial password for user will be 123
