[uClinux-dev] re-mount root filesystem

[advan]

hi,everyone
  I have one embedded device(mips R4000) with Kernel-2.4.25, it boots with a root filesystem in JFFS2 format (/dev/mtdblock1), I would like to switch the root filesystem to another in a RAMDISK with an ext2 filesystem, but I can't umount the JFFS2 root filesystem (device is busy). I tried to use 'fuser' to check who is using / root filesystem , but busybox doesn't support the 'fuser' command. Anyone know how to switch root filesystems, any feedback appreciated. Thank you in advance

Best Regards 
                                            advan
