Hi Onsi,

Well, that’s bad news.



We, and I assume many others as well (like the folks from Stackato who do
it in the public), have used SSHFS + FUSE to implement a persistent file
system for old-fashioned apps/apps that are not Cloud-native. I don’t want
to fight an ideological battle here, it’s just that these apps do still
exist (in majority) and a file system service is an important
service/feature for them.



So if you remove FUSE (which we thought is not going away/was added to
stay), it’s pretty bad for us/many apps.



Best regards, Vedran

+1 - It would be sad to see FUSE support go away. It's been very helpful
for running apps that depend on a persistent FS, like Wordpress. Perhaps
this use case of mounting a remote SSHFS could be supported in some other
way?

Hey CF-Dev,



The Garden team has been hard at work substantially improving
Garden-Linux's security features. Garden-Linux now employs user namespaces
and drops capabilities when creating unprivileged containers - we're
excited to bring both of these features to the platform!



Diego currently runs applications in *privileged* containers. These lack
the security features outlined above and we are planning on switching to
launch all CF applications in *unprivileged* containers.



Unfortunately, it has proved difficult to support
mounting FUSE filesystems from within unprivileged containers. We believe
the security benefits outweigh the features that FUSE give us and* are
planning on removing support for FUSE in favor of better securing our
containers.* If/when FUSE support in unprivileged containers becomes
possible we may add it back to the platform.



Thoughts? Concerns?



Thanks!



Onsi
