[c-nsp] Different bootldr and system versions

[Rick Kunkel]

Sorry about the rapid-fire questions over the past few days.  I can't seem
to find an answer to this.

I've got a newer system image, but not a bootloader for my 6509.  I'm 
considering going from this:

boot system flash sup-bootflash:c6sup22-psv-mz.121-19.E1.bin
boot bootldr bootflash:c6msfc2-boot-mz.121-19.E1.bin

To this:

boot system flash disk0:c6sup22-psv-mz.121-26.E8.bin
boot bootldr bootflash:c6msfc2-boot-mz.121-19.E1.bin

Note the different versions above.  Is this kosher?

BTW, I think when I first started configuring this thing, I left the 
bootloader out entirely and it worked.  Is that viable?

Thanks,

Rick Kunkel
