OpenBSD/sgi、IP26カーネルインストールにまつわるトラブル

! WARNING !
ここに記述してある事は、100%役に立ちません。
完全に備忘録です。

OpenBSD/sgiでIP26のカーネルは正式サポートされていません。
したがって、外部のサイト(ftp.jaist.ac.jp等)から
カーネルの入ったbase57.tgzをダウンロードしても、
IP26のカーネルは含まれていません。

インストール時に、最後に「カーネル無いよ」と警告が出ます。

Writing file /mnt/usr/mdec/boot-IP26
sgivol: stat /mnt/usr/mdec/boot-IP26: No such file or directory

WARNING: Boot install failed. Booting from disk will not be possible

この問題を解決するには、手動でカーネルブートローダーを設置してやる必要があります。
(NFS BOOTは試していません)

処理を行っているのは、

Super User's BSD Cross Reference: /OpenBSD/distrib/sgi/ramdisk/install.md

ですので、まずはboot-IP26を作ってやらなければなりません。

Super User's BSD Cross Reference: /OpenBSD/sys/arch/sgi/stand/boot64/Makefile
Super User's BSD Cross Reference: /OpenBSD/distrib/sgi/iso/Makefile
Super User's BSD Cross Reference: /OpenBSD/distrib/sets/lists/base/md.sgi

に追記をしてリリースイメージ作成時にboot-IP26を作るようにします。

boot-IP26の書き込み方法ですが、
自分は、"WARNING: Boot install failed. Booting from disk will not be possible"のエラーが出ても無視して処理を続行し、
インストール作業を終了させて#が出た後に、

# /mnt/usr/mdec/sgivol -w boot /mnt/usr/mdec/boot-IP26 sd0
Writing file /mnt/usr/mdec/boot-IP26

10:k blocks 17783112 first        0 type  6 (Volume)
# mv /mnt/usr/mdec/bsd.IP26 /mnt/bsd

カーネルの設置とブートローダーの書き込みを行いました。

で、どーやって肝心のboot-IP26やbsd.IP26を持ってくるか?ですが、
ftpで転送をかけました...
が、OpenBSDramdisk kernel内で使えるようにするため?か、
このftpは制限がかかっていて、使いづらい事この上ないです...

どうやってもユーザーとパスワードを設定してftpサーバにログインすることができなかったので、
anonymous ftpサーバをたてました。

ブートローダーとカーネル設置してようやくHDDから起動出来るようになったと思ったら、

応答しません。これはIP26カーネルが不安定なため、

Making all device nodes...sh(8003) in realloc(): error: chunk info corrupted
Abort trap 

インストール時にMAKEDEVが動かないため、/dev/consoleが作られないためです。
しかたがないので、再度ramdisk kernelから起動して、
MAKEDEV stdで/dev/consoleを作ってやります。

どっかのシリーズもののAVみたいなオチがつきましたが、現状そんな感じです。
