Snoop will display the decoded vendor options. The last time I made a comparison, it did a better job than ethereal at making sense of dhcp packets. Normally ethereal has been more helpful, so this was a surprise. > There are DHCP options that the Solaris Express Docs say the Install > uses to find the Install software, sysidcfg, and Jumpstart files, but > for me it's only working if I specify that info as -B <options> in the > GRUB menu.lst file. > > Once the install fails, I can use dhcpinfo manually to look up all thos > options and I get the right values. > > So now I'm trying to see if the Docs are corect, and if the Install > miniroot really checks the Sun Vendor options at all. newboot (grub) on Solaris broke the compatibility between the use of the vendor options between sparc and x86. You really need to specify these in the grub configuration or hack the miniroot to unbreak this compatibility. No space was reclaimed from the miniroot when removing this feature, it seems. I'm just a little bitter because this break came just after I got a cross-platform dhcp config that I was quite happy with. :) -- Mike Gerdts http://mgerdts.blogspot.com/
