/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. > 2) To mount a cdrom I know I can start 9660srv... > but how would I mount another HD? I did not see any other > filesystem servers. 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.)
