Don't export PS1 in /system/etc/mkshrc.
At present, when running a busybox shell ("busybox sh") from mksh (/system/bin/sh), one gets the following message before every command line: sh: precmd: Permission denied This is due to mkshrc exporting a PS1 which depends on a mkshrc defined function, "precmd". Since "busybox sh" does not source mkshrc, it does not have this function defined, resulting in the above error. By not exporting PS1, "busybox sh" uses its own reasonable default. mksh subshells continue to work as usual, since they (re)source /etc/mkshrc anyways.
