Fstab
使用 fstab 掛載 posixovl
以下行:
/path1 /path2 posixovl none 0 0
失敗並出現錯誤:
/sbin/mount.posixovl: invalid option -- 'o' Usage: /sbin/mount.posixovl [-F] [-S source] mountpoint [-- fuseoptions]
這是因為
mount.posixovl
使用了非標準的掛載語法,並且fstab
會假設預設的掛載語法來呼叫它,例如。mount.posixovl /path1 /path2 -o [whatsoever_/etc/fstab_options]
編輯#1: 同樣的問題,在這個 linuxquestions.org Q&A 中用一個更醜陋的黑客解決了,標題為:$$ SOLVED $$如何在啟動時安裝 fuse-posixovl 分區?
我寫了一個包裝器
mount.posixovl
,使它可以與fstab
首先,重命名
/sbin/mount.posixovl
為其他名稱,例如/sbin/mount.posixovl.orig
最後,創建一個
/sbin/mount.posixovl
包含以下內容的新文件:#!/bin/bash # wrapper for mount.posixovl to conform with common mount syntax # with this wrapper posixovl can be used in fstab # location of the original mount.posixovl origposixovl="/sbin/mount.posixovl.orig" # gather inputs while [ $# -gt 0 ]; do if [[ "$1" == -* ]]; then # var is an input switch # we can only use the -o or -F switches if [[ "$1" == *F* ]]; then optsF="-F" else optsF="" fi if [[ "$1" == *o* ]]; then shift optsfuse="-- -o $1" else optsfuse="" fi shift else # var is a main argument sourcedir="$1" shift if [[ "$1" != -* ]]; then targetdir="$1" shift else targetdir="$sourcedir" fi fi done # verify inputs if [ "$sourcedir" == "" ]; then echo "no source specified" exit 1 fi if [ "$targetdir" == "" ]; then echo "no target specified" exit 1 fi # build mount.posixovl command "$origposixovl" $optsF -S "$sourcedir" "$targetdir" $optsfuse
自然,將新創建
/sbin/mount.posixovl
的設置為可執行(chmod +x /sbin/mount.posixovl
)有用的安裝
posixovl
