AUTOUNMOUNTD(8) BSD System Manager's Manual AUTOUNMOUNTD(8)NAME
autounmountd -- daemon unmounting automounted filesystems
autounmountd [-d] [-r time] [-t time] [-v]
The autounmountd daemon is responsible for unmounting filesystems mounted by automountd(8). On startup, autounmountd retrieves a list of
filesystems that have the automounted mount option set. The list is updated every time a filesystem is mounted or unmounted. After a speci-
fied time passes, autounmountd attempts to unmount a filesystem, retrying after some time if necessary.
These options are available:
-d Debug mode: increase verbosity and do not daemonize.
-r Number of seconds to wait before trying to unmount an expired filesystem after a previous attempt failed, possibly due to filesystem
being busy. The default value is 600, or ten minutes.
-t Number of seconds to wait before trying to unmount a filesystem. The default value is 600, or ten minutes.
-v Increase verbosity.
The autounmountd utility exits 0 on success, and >0 if an error occurs.

The autounmountd daemon appeared in FreeBSD 10.1.
The autounmountd was developed by Edward Tomasz Napierala <trasz@FreeBSD.org> under sponsorship from the FreeBSD Foundation.

FSTYP(8) BSD System Manager's Manual FSTYP(8)NAME
fstyp -- determine filesystem type
fstyp [-l] [-s] special
The fstyp utility is used to determine the filesystem type on a given device. It can recognize ISO-9660, Ext2, FAT, NTFS, and UFS filesys-
tems. The filesystem name is printed to the standard output as, respectively, cd9660, ext2fs, msdosfs, ntfs, or ufs.
Because fstyp is built specifically to detect filesystem types, it differs from file(1) in several ways. The output is machine-parsable,
filesystem labels are supported, the utility runs sandboxed using capsicum(4), and does not try to recognize any file format other than
These options are available:
-l In addition to filesystem type, print filesystem label if available.
-s Ignore file type. By default, fstyp only works on regular files and disk-like device nodes. Trying to read other file types might have
unexpected consequences or hang indefinitely.
The fstyp utility exits 0 on success, and >0 if an error occurs or the filesystem type is not recognized.

The fstyp command appeared in FreeBSD 11.0.

Linux uses hdparm to set these parameters, my question is: what tool uses BSD systems (FreeBSD/OpenBSD/NetBSD)? There is another thing which FreeBSD implements on their filesystems: softupdates. If I forgot to enable this option when I partitioned the disk, how could I enable it at a later time? (1 Reply)
