Re: Mount a remote FS as a user

[Daniel Tihelka via systemd-devel <systemd-devel@xxxxxxxxxxxxxxxxxxxxx>]

Hello,
OK, thanks for the clarification.

I was afraid that the situation is like you have described. Still it
surprises me that even the sshfs case cannot be handled by user
instance of systemd ...

Do you have any information that the kernel is going to open autofs
for unpriv clients?
Or, could it be a way to write a d-bus capable daemon (or use/extend
udisks or systemd capabilities?) which would handle the mounts for a
particular user, i.e. a user would provide remote host+fs
type+username+passwd+required mount point+access permissions and the
daemon would mount it then for the user as required. Or has this way a
security flow I don't see?

Thanks,
DT
