NetBSD 絹の日記

DL360/G4 が思ったほど速くない件で /etc/fstab に次のような行を追加して /tmp を tmpfs にして見たら、

tmpfs                   /tmp    tmpfs   rw

(write cache はなくても) CPU はそれなりの稼動をしているが、やはり速くないと確認した。

なお、tmpfs を /tmpfs に載せておいて、更に /export の上にその /tmpfs を mount_union で載せる件は、

mount_union: /tmpfs on /export: Operation not supported

で、だめだった。

実は Xeon と言っても色々あって、以前の Netburst 系は遅い、と nork さんに教わった。

こちらは、速い方の Xeon、多分 Core 系というものなのだろう

何故か、最近、次のように言われる

Debugger entered--Lisp error: (void-variable dir)
  elscreen-e21-command-line()
  command-line-1(("elscreen"))
  command-line()
  normal-top-level()

次のような回避策をして見た
