Chromium のリンク時の ld の引数を記録した
今朝のビルド中，ld (gold) のバグを踏んで "fatal error: out of file descriptors and couldn't close any" となった：
この問題自体は要するに ulimit -Hn 2048; ulimit -n 2048 的なことをしてやれば回避でき，具体的には /etc/security/limits.conf に
* soft nofile 2048 * hard nofile 2048
とか書いてシェルを立ち上げ直す((本当言うと Ctrl-Alt-F1 で getty(8) からログインし，GNU screenを立ち上げてすぐデタッチし， Ctrl-Alt-F7 でウィンドウ・マネージャ内に戻り，再アタッチしてからリンクに再チャレンジ．PAMによる認証のタイミングで設定が発動するらしいので... ちなみにそのGNU screenからは例によってXサーバに接続できなかった．))ことで解決したんだが，そこで興味が沸いて ld の引数を記録してみた．
#!/bin/sh echo "$@" /usr/bin/ld.gold "$@"
結果
