My Frst post here.
Fresh install. So far very impressed.

However, I have a problem mounting my sshfs from autostart.sh

I have a custom sshd_config file allowing only my user, not root.
My sshfs are set up with passwordless -t rsa -b 4096.
I mount them into ~/Network with a subfolder for each separate sshfs.

I have 2 shares (Raid, Blu-Rays). I mount with:

sshfs username@mainpc:/media/Raid /home/username/Network/Raid -o cache_timeout=120
sshfs username@mainpc:/media/Blu-Rays /home/username/Network/Blu-Rays -o cache_timeout=1000

These commands work perfectly from both the run prompt & terminal.
On my other computers, this works perfectly with Gnome Startup Applications under Debian, SUSE, & BSD.
I have also had this working perfectly a couple of weeks ago under Sid/OpenBox calling from autostart.sh exactly as I am trying to do right now.

For some reason, it just won't work for me.
The sshfs shares actually do mount, but the desktop hangs for a few seconds (no panel, no conky) until autostart.sh finishes, then dumps me back at the login screen.
At the login screen, I can Ctrl-Alt-F1 to get to tty1. There I log in & find that the shares are mounted & browsable.
The desktop just keeps dumping me at the login screen until I either remove or comment the two sshfs lines from autostart.sh

Without the offending lines the desktop takes 5 seconds to load, so I've given them plenty of delay.
I thought maybe it didn't like my syntax, so I tried it a few different ways:

(sleep 11 && sshfs username@mainpc:/media/Raid /home/username/Network/Raid -o cache_timeout=120)

sh -c "sleep 11 && sshfs username@mainpc:/media/Raid /home/username/Network/Raid -o cache_timeout=120"

I even tried writing two different executable .sh scripts in my home folder using both "!/bin/sh -e" & "#!/bin/bash"
...and calling them from autostart.sh with:

sleep 11 && bash /home/username/path/script.sh

...then I tried:

(sleep 11 && bash /home/username/path/script.sh)

...then I tried:

sh -c "sleep 11 && bash /home/username/path/script.sh"

ALL with EXACTLY the same result.
Panel & Conky don't load, then once the script finishes I get dumped at the login screen.
Once I remove any call to sshfs or script.sh from the autostart.sh file, everything works correctly and Panel & Conky load within 5 seconds.

As I said, I have had this working on OpenBox before on an install I did a few weeks ago starting with a minimal Debian.
So, wtf am I doing worng ?

Any suggestions for other ways to load the sshfs at startup ?
I can't use rc.local to do it because, as I said, I have disallowed root in my sshd_config
Questions ?
Suggestions ?
