Yes, I just meant as user-point-of-view intermediate.

"storeio --store-type=part 1:device:hd0" apparently supports
file_get_storage_info and reports the partition boundaries there,
so the I/O would not have to go through the storeio translator.

libstore/encode.c (too_big) has a comment saying "The RPC
protocol uses 32-bit off_t's" but that is false since 2002.

But the installer does not use it, for flexibility.

But storeio can be used as an intermediate between the two.

But what is actually linked against libparted is libstoreio, which is
shared between storeio and ext2fs. So we'd need two different
libstoreio, one with parted support, the other without.

Package: hurd
Version: 1:0.8.git20160826-1
Severity: serious
File: /hurd/ext2fs.static

The ext2fs translator contains GPLv2-only code copied from Linux,
but it is linked (through libstore) with libparted, which is
GPLv3-or-later since 2007.  This combination violates at least
one of the licenses.  The problem is clearest in ext2fs.static
but FSF doctrine is it applies to dynamic linking as well.

One of the Hurd developers acknowledged in August 2007 that
ext2fs in the Hurd contains GPLv2-only code:
https://lists.gnu.org/archive/html/bug-hurd/2007-08/msg00073.html

The "BSD-licensed liblabel" was suggested as a replacement of
libparted, on the #hurd IRC channel on 2016-09-15.
Until that is implemented, the partition-table support in
libstore could be disabled altogether, because GNU Mach currently
provides a named device for each partition.
