Pass-through FUSE mount options #6
Description
Mount options to FUSE appear to be hard-coded (eg: default_permissions)
This makes it difficult to expose a catfs mount for use in a docker container from the host; docker tries using it's overlayfs as root, but fails since the catfs mount isn't mounted with allow_other or allow_root.
Here's an example of what I'm trying to run with:
RUST_LOG=catfs=debug,fuse=debug,integration_tests=debug \
/usr/local/bin/catfs /mnt/source /data/cache /mnt/dest \
-o rw,allow_other,umask=002,gid=1000,uid=1000,syslog,dev,suid
## Output from `catfs`
