Since I have a lot of apps, every one of them is telling me that my disk is full. So i decided to move them all and create a symlink to the media partition.
in SSH I did:
mkdir /private/var/root/ROOT_Applications
cp -r /Applications/* /private/var/root/ROOT_Applications
rm -rf /Applications && ln -s /private/var/root/ROOT_Applications /Applications
Everything works, the link works. But when I reboot. No more apps. Nothing, and I'm unable to connect through ssh.
that sounds like a permissions problem. move it to somewhere other than /private/var/root. the mobile user probably can't view them in root's home folder.
edit: yes, i can't enter root's folder when logged in as mobile.
