[LEDE-DEV] sysupgrade weakness

[reiner otto]

sysupgrade is "weak", when having to kill user processes before flashing. Having spent several hours, to figure out, why only a reboot was done, I recognized, that sysupgrade "promises" to kill my private running processes, but does not succeed in doing so. Manual "kill -9 ..." before running sysupgrade fixed the issue.
At least, it might be a good idea for sysupgrade to give a warning, in case killing the processes does not succeed, to have a clue.
