You usually mount a filesystem to a folder in /n. Just use that
folder as you would do the rest of the filesystem.

/bin is NOT a mounted directory. It is a bound directory. /bin would
be bound to four places:
	- /$objtype/bin - system executables
	- /rc/bin - system shell scripts
	- $home/bin/$objtype - user executables
	- $home/bin/rc - user shell scripts
You choose. See bind(1) for details.

Depends on the filesystem. If it's fossil, see fossil(4). If it's FAT
on USB, use usbfat: The choices are endless, if you know how.

/bin is an empty directory that is then populated by a sequence of binds (you
can find them in /lib/namespace and your own lib/profile).  so first you work
out which one of those you'd like to hold the file (ie, global or just your own private bin).
it will typically be one of /$objtype/bin or $home/bin/$objtype for compiled programs
and /rc/bin or $home/bin/rc for rc scripts.  copy the new command to one of those.

in general, given a union mount, files are created in the top-most bind or mount that
was bound or mounted using the -c option to allow creation.  none of the files
bound to /bin have that option so the resulting directory disallows creation.

having typed all that in i see that pietro gagliardi has already answered but i'll send this anyway.

if a program's primary purpose is to act as a file server, it can be found in section 4 of
the manual, so have a browse through that.  some others, including those in ndb(8)
provide a service by serving some files, but that's just the interface so they are documented
wherever the service would naturally belong.  (section 8 is admin, which must surely include DNS.)

Thank you I have now downloaded the manual
