lsvfs -- list installed virtual file systems
lsvfs [vfsname ...]
The lsvfs command lists information about the currently loaded virtual
file system modules. When vfsname arguments are given, lsvfs lists
information about the specified VFS modules. Otherwise, lsvfs lists all
currently loaded modules. The information is as follows:
Filesystem the name of the file system, as would be used in the type
parameter to mount(2) and the -t option to mount(8)
Num the filesystem type number.
Refs the number of references to this VFS; i.e., the number of
currently mounted file systems of this type
Flags flag bits.
mount(2), getvfsbyname(3), getvfsent(3), mount(8)
A lsvfs command appeared in FreeBSD 2.0.
In DragonFly's encrypted root setup, lsvfs will show at least 2
references to ``ufs'' even though just /boot seems to be mounted. The
second reference is the initial root from the /boot/kernel/initrd.img.gz
