mkarchiso: do not hardcode airootfs image filename in _mkchecksum and _mksignature
The image file name is set by the appropriate _mkairootfs_${airootfs_image_type}
function. It's wasteful to check all possible file names in _mkchecksum
and _mksignature
. Instead, the the value could be reused.
An issue with this is that, if _mksignature
fails, re-running mkarchiso will result in the variable not set, because _prepare_airootfs_image
has:
_run_once "_mkairootfs_${airootfs_image_type}"
