If you specify the -N and -v options with newfs, you’ll see output that details the resulting mkfs command and the parameters that would be used in creating a file system without creating it. Similarly, the mkfs command with a -m parameter reveals the parameters of an existing file system, as shown here: # mkfs -m /dev/rdsk/c0t2d0s2 mkfs -F ufs -o nsect=80,ntrack=19,bsize=8192,fragsize=1024, Making Smart Decisions about File Systems cgsize=32,free=4,rps=90,nbpi=4136,opt=t,apc=0,gap=0,nrpos=8, maxcontig=16 /dev/rdsk/c0t2d0s2 4023460 Note that the mkfs command includes a parameter for the type of file system.

To simplify maintenance of your automount maps, the automounter provides a number of variables that take the place of literal entries. The variable ARCH, for example, represents the architecture of a particular machine.

Other file systems are mounted later in the boot process, as configured in the /etc/vfstab file. Still others are mounted only as requested via a mount command or, as previously mentioned, in response to requests via automounter. The /etc/vfstab file specifies file systems to be mounted along with locations and options. d/ mountall. , readonly) Here is a sample /etc/vfstab file: #device #to mount /proc fd swap /dev/dsk/c0t3d0s0 device to fsck /dev/rdsk/c0t3d0s0 mount point /proc /dev/fd /tmp / FS type procfs fd tmpfs ufs fsck pass 1 mount at boot no no yes no mount options - Making Smart Decisions about File Systems /dev/dsk/c0t3d0s6 /dev/rdsk/c0t3d0s6 /usr /dev/dsk/c0t3d0s5 /dev/rdsk/c0t3d0s5 /opt /dev/dsk/c0t3d0s1 - ufs 2 ufs 5 swapfs - no yes no - NFS server support is not provided (by default) until run state 3 (discussed in Chapter 4).
