# This is ugly.
#   We need to sudo su - sdk -c so the SDK user gets a fresh login.
#    'sdk' is member of multiple groups, and plain docker USER only
#    allows specifying membership of a single group.
#    When a command is passed to the container, we run, respectively:
#    sudo su - sdk -c "<command>".
#   Then, we need to preserve whitespaces in arguments of commands
#    passed to the container, e.g.
#    ./update_chroot --toolchain_boards="amd64-usr arm64-usr".
#    This is done via a separate ".cmd" file since we have used up
#    our quotes for su -c "<cmd>" already.
