Problem: dhcpcd wouldn't run with config files, only when configured on command line
Solution: the format given in the example config file in /etc/dhcpc seems to either be incorrect or, at least, it doesn't work for my ISP (@home). The format _given_ is as follows: OPTIONS='-h "(hostname)"' This doesn't work for me. I have to do it this way: OPTIONS='"-h (hostname)"' So it turned out to be really simple after all. Thanks for the responses! Andrew W.
