old thread here, though it seems to be including a number of tangents.

This version is pretty simple to use, but not 100% complete.

--> requires Hijack v328 or newer.
--> you should manually "pause" your player first, or put it in stand-by mode.
--> after "upgrader" completes, you must manually reboot your player.
--> after the reboot, you should run emptool or emplode to rebuild the database

mark, can't you just modify the program to send a SITE command to the ftp daemon to make sure the player is off before uploading the upgrade? i.e.:

make_ftp_cmd(cmd, ftp_user, ftp_passwd, "-Y \"site button top.L"", empeg_host, "/dev/null");

though i'm not sure what the effects would be if the player was off already
