to Alt-F
Hello,
got a quirk after moving the Alt-F folder around and did not found information where it is coming from. Every kind of login to a known user on the Alt-F box with a ssh service sftp, scp did give a line: id: unknown ID 1000
The user id and group do exist in /etc/passwd and /etc/group and match the clients id. It appears on 3 clients without any changes on them, so it must be Alt-F related on my box and appears on all defined users that had worked before. As result the gnome-vfs and fuse is unable to mount these services and fail. Here is a plain login verbose, can someone see a bug there?

to Alt-F
Just found out what went wrong here, so i want to share to help others if the same bug appears. Mind that it appears after using the Package->Alt-F function to copy Alt-F to another partition.
So what happened is a lost of permissions on the copy, so that /etc/passwd and /etc/groups was owned by 0,0. This points to a general linux problem described here: http://www.linuxquestions.org/questions/linux-embedded-and-single-board-computer-78/whoami-unknown-uid-1000-a-4175447881/
As stated in the article a chmod 644 (as root) to the /etc/passwd and /etc/group has repaired the problem for me.
Open question: Is there a bug within the copy function in 0.1rc5 , that the permissions getting lost from copy operations?

I couldn't reproduce that.
I performed the copy using the Alt-F Package Manager webUI, and the files ended up with the right permissions, so I don't thing it is a bug (the copy is performed using the 'cp -a' command)
Thanks anyway
Eric
