/etc/filesystems 存放這許多檔案系統的所有資訊,許多元護檔案系統的指令都是從這個檔案中擷取的檔案系統的預設屬性。此檔案的格式是stanza 格式的。包含檔案系統的名字和屬性。

dev = /dev/hd4 --檔案對應的邏輯裝置,邏輯卷
vfs = jfs2 -- mount的類型
log = /dev/hd8 ---檔案系統的日志裝置。該項隻對jfs 和jfs2 有用。
mount = automatic --檔案系統預設安裝方式
1 automatic
2 true 用mount all 指令安裝,用unmount all 解除安裝檔案,系統初始化時自動執行 mount all。
3 false 檔案系統不會自動安裝,必須手動安裝(用mount 指令單獨安裝)
4 readonly 檔案系統以隻讀的方式安裝
check = false --檔案系統是否由fsck 指令在預設情況下檢查。
type = bootfs --檔案系統類型,用于按類型分組安裝檔案系統。mount -t type
vol = root --檔案系統的卷标
free = true --
