I've got a head scratcher and hoping this group can help me figure out what I'm missing. I suspect it is a glaring user error 
First, my setup (like many of you too) is a little complicated. I use rclone to mount a google drive. most of the contents of that drive is encrypted using encfs. Usually when I mount, I also do a union (either through unionfs or an rclone union) with a matching local folder (also using encfs).
It usually looks like this:
google drive encrypted --> ~/.cloud
encfs ~/.cloud decrypted --> ~/cloud
local encrypted --> ~/.local
encfs ~/.local decrypted --> ~/local
union of ~/cloud and ~/local --> ~/media
I mount this setup on a few macOS machines and on several Ubuntu machines (sometimes on the same machine but under two different users)
On Ubuntu, under a specific user, I mount my google drive with a path, like this:
barsmusicrw:encmedia/XgksGASDkelsFDF-Fkdk4skf --> ~bar/.cloud
(barsmusicrw is for that specific user, mount is a read/write ... that encrypted text is made up for this post, but is similar in style and length to my encfs filenames)
Elsewhere, I mount the same google dive this way:
gdrive:encmedia --> ~foo/.cloud
User Foo wants the entirety of encmedia while user Bar only wants the contents of the decrypted XgksGASDkelsFDF-Fkdk4skf folder.
For the sake of this post, let's say XgksGASDkelsFDF-Fkdk4skf decrypts to Tunes
Note that none of these are using caching. In all instance, I use these flags:
--config=$R_CONFIG --dir-cache-time 1h --drive-chunk-size 32M --log-level INFO --timeout 1h --umask 002 --daemon
(where $R_CONFIG is the path to the config file)
config for user Bar
[coritunesrw]
type = drive
client_id = redacted
client_secret = redacted
scope = drive
token = {"access_token": redacted}
root_folder_id = AyEskifEovsFVSEf
config for user Foo
[gsuite]
type = drive
client_id = redacted
client_secret = redacted
token = {"access_token": redacted}
chunk_size = 16M
root_folder_id = AyEskifEovsFVSEf
To my eye, they are nearly identical. They actually use the same access tokens, FWIW
Here's the rub:
For user Bar, I see about 100 files in both ~/.cloud and ~/cloud. I see the same number of files in the web interface of Google Drive too. In google Drive, the encrypted filenames match up. EG: what I see in ~/.cloud is what I see in drive/XgksGASDkelsFDF-Fkdk4skf
For user Foo:
in both ~/.cloud and ~/cloud I see 5 files. I've tried unmounting and remounting, I've rebooted...tried other machines using Foo's config.
Anyone have any idea what Bar is seeing the right files but Foo isn't? Could it be some sort of caching that I'm not accounting for? It's been over 24 hours since the last rclone sync so I'd think my 1 hour timeout and dir-cache-time wouldn't be the issue.
I'd be grateful for any tips - this one was a hard to document and explain as it is to wrap my head around
