Wiping Boot before Flashing ROMs?

[dmo580]

I was interested in using this script because I used it on my Nexus S and it was highly recommended:

It wipes /data, /cache, /boot, and /system.

I noticed that in CWM on my Nexus S I could go to Mounts/Storage and wipe /system and /boot. I usually do a factory reset also to cover /data and /cache.

Now on the SGS2, I noticed most recoveries only have wipe /system. What accounts for this difference? Is it bad to wipe /boot on our SGS2?

Yes. Don't touch bootloader unless you have a specific reason for doing same. If you wipe/trash/bork your bootloader there's a fair chance you'll hard brick your phone & need it JTAG'd.

/boot contains the bootloader?

how come it gets wiped on other phones like the Nexus S?
