app-backup/borgbackup-1.2.0::gentoo was built with the following:
USE="" PYTHON_TARGETS="python3_10 -python3_8 -python3_9"
dev-python/pyfuse3-3.2.1::gentoo was built with the following:
USE="-test" PYTHON_TARGETS="python3_10 -python3_8 -python3_9"

WORKAROUND
-----------

[2]genr8too / # emerge -u1 dev-python/llfuse

These are the packages that would be merged, in reverse order:

Calculating dependencies... done!
[ebuild  N     ] dev-python/llfuse-1.4.1::gentoo  USE="-doc -examples -test" PYTHON_TARGETS="python3_10 (-pypy3) -python3_8 -python3_9" 757 KiB

Total: 1 package (1 new), Size of downloads: 757 KiB

Would you like to merge these packages? [Yes/No] Y

dev-python/llfuse-1.4.1::gentoo was built with the following:
USE="-doc -examples -test" PYTHON_TARGETS="python3_10 (-pypy3) -python3_8 -python3_9"

SUCCESS!
---------

genr8too / # mount -t fuse.borgfs /mnt/borg/gentoo-nvme1n1p7::2022-04-27 /mnt/gentoo2/
Enter passphrase for key /mnt/borg/gentoo-nvme1n1p7:
genr8too / #

Reproducible: Always



Expected Results:  
the .ebuild for borgbackup has DEPENDS on dev-python/pyfuse3 but it also apparently needs DEPEND on dev-python/llfuse for the mounting to actually work.
Comment 1 Michael Egger 2022-06-16 14:02:29 UTC
Same here, manually installing dev-python/llfuse helps as suggested
Comment 2 Piotr Karbowski (RETIRED) gentoo-dev 2022-06-19 13:59:34 UTC
We did switched to pyfuse3 as per borg recommendation and it should work there. Looking into it.
Comment 3 Piotr Karbowski (RETIRED) gentoo-dev 2022-06-19 14:04:06 UTC
It is related to pyfuse3 being currently broken with Python 3.10

>>> import pyfuse3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /usr/lib/python3.10/site-packages/pyfuse3.cpython-310-x86_64-linux-gnu.so: undefined symbol: _PyGen_Send

And is not, in fact, borg problem. You might as fallback install dev-python/llfuse unit its resolved or call borg with Python other than 3.10.
