Looking at mount(8), it seems that the normal way is for ‘source’ to be something like “knuth.cwi.nl:/dir”. The kernel then takes care of parsing that and doing name resolution somehow. In that case, we don’t have anything to do, good for us. mount(8) doesn’t mention ‘addr’. Do you have documentation about it? Thanks, Ludo’.
