I'm posting here as I wasn't sure which board this fits in. I currently use unionfs to combine local files /rclone_upload/google_vfs with gdrive files I mount using rclone /mount_rclone/google_vfs :
unionfs -o cow,allow_other,direct_io,auto_cache,sync_read /mnt/user/rclone_upload/google_vfs=RW:/mnt/user/mount_rclone/google_vfs=RO /mnt/user/mount_unionfs/google_vfs
I'd like to switch to MergerFS as it supports hardlinking, whereas Unionfs doesn't. I've installed unionfs via Nerd Pack - c
