I've been using Doozan mtd0 uboot for months now without problems.  As 
far as I can see the only risk is a power lost during the the loading of 
the new boot.  Then you would need jtag to recover from this.   I've 
reinstalled it several times (>10) without  problems; Haven't tripped 
over the power cord during reinstall yet!
