mount jffs2 filesystem from /etc/fstab with user permissions - linux-kernel

Question

My rootfs is squashfs and I am trying to mount three JFFS2 partition on my flash device. But I want to set permissions for those partitions/directories.
The requirement is /readerconfig is only accessible by user with id
1001. /platform is only accessible by user with id 1001 /apps is only accessible (read,write and execute) by user with id 1000.
Below is my fstab entry.
rootfs / squashfs defaults 0 0
proc /proc proc defaults 0 0
/dev/mtdblock12 /readerconfig jffs2 rw,umask=0077,uid=1000,gid=1000,exec,noatime 0 0
/dev/mtdblock13 /platform jffs2 rw,umask=0077,uid=1000,gid=1000,exec,noatime 0 0
/dev/mtdblock15 /apps jffs2 rw,umask=0077,uid=1001,gid=1001,exec,noatime 0 0
tmpfs /var tmpfs mode=0777 0 0
tmpfs /tmp tmpfs mode=0777 0 0
sysfs /sys sysfs nosuid,noexec,nodev 0 0
/dev/mtdblock14 /etc jffs2 rw,mode=0777,uid=0,gid=0,noatime 0 0
Upon implementing, I found that the mount options like uid and gid are not set for JFFS2 file system mount points.
Here is the output of mount command on the target board.

How do I set permissions for the directories /readerconfig, /platform and /apps directory?
Is it limitation of JFFS2 / mount command? or I can do it from rcS script? All alternatives are invited.

Jffs2 based mount point cannot be set with permissions. One has to change ownership using 'chown' command and/or set permissions using 'chmod' command.
