NAS326, auto execute command at startup

The magic trick used by Tweaks and RandomTools is that they are zypgs, installed in the normal way (apart from the MetaRepository injector), and so they are started regularly by the firmware package manager.

Fortunately for you there is another way. The packages are started by /etc/init.d/zypkg_controller.sh, and this script contains this snippet:

[code]

ZYPKG_PKG_SRC_PATH="/i-data/.system/zy-pkgs"
<snip>
USRPKG_DEPS_START="${ZYPKG_PKG_SRC_PATH}/USRPKG_DEPS_START"
<snip>
case "$1" in
"start" )

<snip>
    # - start to startup packages according to ${USRPKG_DEPS_START}
    while read zypkg; do
        bname=`basename ${zypkg}`
        zypkg=${ZYPKG_PKG_SRC_PATH}/${bname}
        Processed_Packages=${Processed_Packages}:${bname}
        write_log "- starting package \"${bname}\" ..."
        #ckeck ZYPKG_DEPS format
        CHKVERSION=`grep "/i-data/" ${zypkg}`
        if [ "$?" != "0" ]; then
            PKGVOLPATH=`grep ${bname} ${PKGSTATUSFILE} |grep "Installed-Rule" |awk -F":" '{print $2}' |sed 's/\/$//g' |sed 's/ //g'`
            zypkg=${PKGVOLPATH}/etc/init.d/${bname}
        fi
        if [ ! -x ${zypkg} ]; then
            write_log "---> Error: start-up program \"${zypkg}\" is not existed or not excutable"
        else
            ${zypkg} startup
            if [ "$?" == "0" ]; then
                write_log "---> start \"${bname}\" successfully."
            else
                write_log "---> start \"${bname}\" failed."
            fi
        fi
    done < ${USRPKG_DEPS_START}
[/code]

So basically it reads the file /i-data/.system/zy-pkgs/USRPKG_DEPS_START line by line, each line is considered to be a filename, the directory is stripped, and /i-data/.system/zy-pkgs/ put in front. If the resulting filename is executable, it is executed with 'startup' as argument.

So create an executable script in /i-data/.system/zy-pkgs/, and put it's name in /i-data/.system/zy-pkgs/USRPKG_DEPS_START (which doesn't exist by default).

You can also use /i-data/.system/zy-pkgs/USRPKG_DEPS_SHUTDOWN to shutdown your stuff cleanly on nas shutdown.
