I use mkfs.jffs2 to generate a partition out of a directory tree (not
the hole root-filesystem).
It seem the owner of the root point of this directory tree is always
root:root, althouh it might have other owners.
Example
mkfs.jffs2 -lnp -e 0x20000 -r /opt/rootfs/opt -o /mnt/hgfs/share/fs_opt.jffs2
In my NFS-rootfs /opt/rootfs/opt is owned by user but flashing the
created jffs file will be mounted as owner root.
>From my point of view this is a bug, as it doesn't care about the real
owner of this part of filetree.
Or did I misused the -r option?
I hope you can give me a comment or some feedback, how to change this behaviour.
Best regards
Arno

Sounds like a bug. I'll take a look at this as soon as I have some time. Or you can send a patch. -- Best Regards, Artem Bityutskiy (Артём Битюцкий) ^ permalink raw reply [flat|nested] 10+ messages in thread

But this is for ubifs, while I detected this bug in jffs2 - this is what I am using. So I can't test this. Best regards Arno ^ permalink raw reply [flat|nested] 10+ messages in thread

Just a broad hint for David ;) (or someone else who has the ability). If It would be just for me, I wouldn't push.

(I just compiled the head) The infomation about the owner for the mount point seems not to be part of jffs2 To make this situation more clean: My flash has 2 partitions / and /opt And I also create two jffs2 files, one for each partition: root.jffs2 and opt.jffs2 If I mount /opt - the ownership of /opt is root, although it has been "user" in the tree I generated the jffs2 files from.
