# in the units of this field. Debian Policy defines this field in units of
# kibibytes:
# The disk space is given as the integer value of the estimated installed
# size in bytes, divided by 1024 and rounded up.
# However, opkg apparently attempts to convert this value from bytes to
# kibibytes in its determination of whether the package's data will fit on
# the system:
# pkg_size_kbs = (pkg->installed_size + 1023)/1024;
# TODO: Further investigate opkg's disk space calculation and, if necessary,
# patch opkg and submit a bug report.
