dig +bufsize

[Cricket Liu]

Regardless of what I specify as an argument to dig's
+bufsize option, dig reports that it advertised a
buffer size of 4096:

$ dig @k.root-servers.net. +bufsize=1024

; <<>> DiG 9.2.0 <<>> @k.root-servers.net. +bufsize=1024
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 27506
;; flags: qr aa rd; QUERY: 1, ANSWER: 13, AUTHORITY: 0, ADDITIONAL: 14

;; OPT PSEUDOSECTION:

;; QUESTION SECTION:

$ dig @k.root-servers.net. +bufsize=2048

; <<>> DiG 9.2.0 <<>> @k.root-servers.net. +bufsize=2048
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 52642
;; flags: qr aa rd; QUERY: 1, ANSWER: 13, AUTHORITY: 0, ADDITIONAL: 14

;; OPT PSEUDOSECTION:

;; QUESTION SECTION:
;.                              IN      NS

So does +bufsize just set the corresponding option to 4096
regardless?
