Yup. Odd pathologies like hardware errors while installing files
are not handled as gracefully as possible because there's no way to
precompute the condition. Even in the odd case, the failing package (which
now renames temp files into place) is backed out, any paired removal
of the old packaghe on upgrade is skipped, and the transaction is
terminated in the middle.
