NetBSD avalon.blip.town 11.0 NetBSD 11.0 (GENERIC) #0: Thu Jul 30 15:23:12 UTC 2026  mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64
>Description:
After creating a dump(8) file on a mount_psshfs(8) mount, using restore(8) on that mounted file will hang indefinitely.
>How-To-Repeat:
# mount_psshfs user@host /mnt/backup
# dump -0f /mnt/backup/root.dump.0 /
# restore -i f /mnt/backup/root.dump.0
restore> add FILE
restore> extract

>Fix:
Use a ssh tunnel instead of mount_psshfs.
