I'm using busybox in an embedded device. The built-in busybox is rather limited. So I want try to replace busybox in place with new, more complete version. I find some info about replacing Busybox on device use serial communication and command line, this also requireds to a http server on LAN. The part of commands
route add -net 192.168.15.0/24 eth0 mount -t tmpfs -o size=2M,mode=0755 tmpfs /mnt cd /mnt wget http://192.168.15.10/busybox-armv5l chmod +x busybox-armv5l
Two points isn't clear here: new busybox does not replace the existing version, instead it's added into another location as an additional busybox? Second, the new busybox is placed into tmpfs in RAM: so its not saved permanently in the partition, and deleted after a reboot? Am I correct?
