For\n swap partitions, this field should be specified as \u2018none\u2019. If the name of the mount\n point contains spaces these can be escaped as \u2018\u000040\u2019.\n \u6307\u5b9a\u6302\u8f7d\u70b9\nThe third field, (fs_vfstype), describes the type of the filesystem. \n \u6307\u5b9afs\u683c\u5f0f\nThe fourth field, (fs_mntops), describes the mount options associated with the\n filesystem. \n \u6307\u5b9a\u6302\u8f7d\u9009\u9879\nThe fifth field, (fs_freq), is used for these filesystems by the dump(8) command to\n determine which filesystems need to be dumped. If the fifth field is not present,\n a value of zero is returned and dump will assume that the filesystem does not need\n to be dumped.\n \u4f9bdump\u7528\nThe sixth field, (fs_passno), is used by the fsck(8) program to determine the order\n in which filesystem checks are done at reboot time. The root filesystem should be\n specified with a fs_passno of 1, and other filesystems should have a fs_passno of\n 2. Filesystems within a drive will be checked sequentially, but filesystems on\n different drives will be checked at the same time to utilize parallelism available\n in the hardware. If the sixth field is not present or zero, a value of zero is\n returned and fsck will assume that the filesystem does not need to be checked.\n \u4f9bfsck\u7528\uff0croot\u662f1\uff0c\u5176\u4ed6\u7684fs\u662f2<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
