NULLFS(4)

🌸 NAME 🌸

okay so bestie, this is NULLFS(4) — the null file system page — and it's giving tiny-but-mighty kernel-module energy 💅✨

✨ SYNOPSIS ✨

To enable support for this driver, place the following line in the kernel configuration file:

options NULLFS

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

nullfs_load="YES"

💅 DESCRIPTION 💅

The nullfs driver will permit the FreeBSD kernel to mount a loopback file system sub-tree. That's the whole main-character move, no cap 🦋

🎀 EXAMPLES 🎀

To mount a nullfs file system:

mount_nullfs /usr/ports /home/devel/ports

It is also possible to define an entry in fstab(5) that looks similar to:

/usr/ports      /home/devel/ports       nullfs          rw      0       0

🦋 SEE ALSO 🦋

• fstab(5)
• mount_nullfs(8)

⭐ HISTORY ⭐

The nullfs layer first appeared in 4.4BSD. Vintage but still serving looks 👑

👑 AUTHORS 👑

• The nullfs kernel implementation was written by John Heideman.
• This manual page was written by Daniel Gerzo <danger@FreeBSD.org>.
