# WARNING WARNING WARNING WARNING
#
# This script is an example to start a new AGL container
#
# You should customize it to fit your environment and in particular
# adjust the paths and permissions where needed.
#
# Note that sharing volumes with host system is not mandatory: it
# was just added for performances reasons: building from a SSD is
# just faster than using the container filesystem: that's why /xdt is
# mounted from there. Same applies to ~/mirror and ~/share, which are
# just 2 convenient folders to store reference build caches (used in prepare_meta script)
