On Alpha the bootpd does not work, it assert-fails on the
size of the struct bootp being != to BP_MINPKTSZ.
A bit of debugging reveals:
alpine#./bootpd -d9
sizeof struct bootp=312, BP_MINPKTSZ=300
bootpd: info(6): bootptab mtime: Fri Oct 29 20:10:09 1999
bootpd: info(6): reading "/etc/bootptab"
bootpd: info(6): read 1 entries (1 hosts) from "/etc/bootptab"
My best bet is that the Alpha alignment inside the struct results
in a bigger bootp struct. I am, however, not sure on what the right
way is to fix this.
Comments appreciated,
Wilko
