Thanks, but would it maybe be possible to find a better solution? I've
been using SSHFS for a while now, and this particular issue is pretty
annoying in practice. How about any of the following:
- When connecting over SSHFS, ask the remote host (via SSH) for the
home directory and cache the result.
- Allow the user to configure a per-host static home directory (i.e.
just a customizable mapping from hosts + users to home directories). I
regularly only connect to 2 hosts with known hostnames and home
directories, so at least for me maintaining such a mapping would be
feasible.
WDYT?
