replicant-frameworks_native/cmds/dumpstate/dumpstate.c
Ken Sumrall 8f75fa7bcf Do not use su to run the df command in bugreports 
User builds do not have su, so when the bugreport attempts to report
disk free space, the command fails and nothing is reported.  However,
the df command does not need to be run as root to report free space,
so just run the command directly.
