post-mount do't work for JFFS

[Aleksey Popov]

Firmware:380.57, 378.54_2
Entware instaled on jffs through patched entware-setup-jffs.sh script (PART_TYPES='ext2|ext3' -> PART_TYPES='ext2|ext3|jffs'). While instaled only base Entware packages (and xupnpd+liblua) post-mount work fine.
When I add additional packages :

admin@RT-N66U-2EF0:/tmp/home/root# opkg list-installed
findutils - 4.5.14-1
ldconfig - 0.9.32-2
libc - 0.9.32-2

liblua - 5.1.5-1
libpthread - 0.9.32-2

xupnpd - 404-1a

post-mount does not start.
Modified post-mount :

#!/bin/sh

i=10; until [ -f /tmp/syslog.log ]; do i=$(($i-1)); if [ "$i" -lt 1 ]; then exit; fi; sleep 1; done

logger -t $(basename $0) "Started for $1"

if [ $1 = "/jffs" ]
then
  ln -nsf "$1"/entware /tmp/opt
  if [ $? -eq "0" ]; then
    logger -t $(basename $0) "Entware dir linked to /opt."
    else  logger -t $(basename $0) "Unable to link Entware dir to /opt."
    fi
  fi

After some time (~ 2 min):

admin@RT-N66U-2EF0:/tmp/home/root# cat /tmp/syslog.log |grep post-mount
admin@RT-N66U-2EF0:/tmp/home/root#
admin@RT-N66U-2EF0:/tmp/home/root# cat /tmp/syslog.log |grep services-start
Aug  1 03:00:13 custom script: Running /jffs/scripts/services-start
Feb 25 00:51:26 services-start: Could not start Entware services.

After a manual run :

admin@RT-N66U-2EF0:/tmp/home/root# /jffs/scripts/post-mount /jffs

admin@RT-N66U-2EF0:/tmp/home/root# cat /tmp/syslog.log |grep post-mount
Feb 25 00:53:31 post-mount: Started for /jffs
Feb 25 00:53:31 post-mount: Entware dir linked to /opt.
