Whenever you mount or unmount a file system, the /etc/mnttab (mount table) file is modified with the list of currently mounted file systems. You can display the contents of this file by using the cat or more commands. However, you cannot edit this file. Here is an example of an /etc/mnttab file:
$ more /etc/mnttab rpool/ROOT/zfs509BE / zfs dev=4010002 0 /devices /devices devfs dev=5000000 1235087509 ctfs /system/contract ctfs dev=5040001 1235087509 proc /proc proc dev=5080000 1235087509 mnttab /etc/mnttab mntfs dev=50c0001 1235087509 swap /etc/svc/volatile tmpfs xattr,dev=5100001 1235087510 objfs /system/object objfs dev=5140001 1235087510 sharefs /etc/dfs/sharetab sharefs dev=5180001 1235087510 fd /dev/fd fd rw,dev=52c0001 1235087527 swap /tmp tmpfs xattr,dev=5100002 1235087543 swap /var/run tmpfs xattr,dev=5100003 1235087543 rpool/export /export zfs rw,devices,setuid,nonbmand,exec,xattr,... rpool/export/home /export/home zfs rw,devices,setuid,nonbmand,exec,... rpool /rpool zfs rw,devices,setuid,nonbmand,exec,xattr,atime,dev=4010005 1235087656 |
