• [備忘] Ubuntu 沒有 root 預設密碼，雖然有 sudo ，但 sudo 有兩個的困擾：
  • (1) 時間問題(sudo timeout): NTP更新或手動改時間的時候會造成
  • (2) hostname 問題: 如果有改 hostname, sudo 也會失效
• [小問題] Windows XP 是 FAT32 格式必須轉換到 NTFS 格式

  convert d: /FS:NTFS 
  convert c: /FS:NTFS
  

• [備忘] 本機加完使用者之後，必須手動跑 YP 的帳號更新

  # make -C /var/yp
  

• [] 更新 Netboot Image

  # /opt/drbl/sbin/mknic-nbi
  

  • [密技] 如果想要自己加東西到 pxe-initrd 的 initial RAMDisk 的話，可以改 /usr/lib/mkpxeinitrd-net/initrd-skel 的內容，例如想要加 NFSv4 或者把 Lustre、AoE、iSCSI 的網路硬碟，可以改 /usr/lib/mkpxeinitrd-net/initrd-skel/sbin/udhcpc-post 這些程序。
