It makes a bit more sense to rely on previous configuration (/etc/conf.d/hostname) and write a tiny 'script' that populates /etc/hostname. bash could do it (naively) in two lines: source /etc/conf.d/hostname echo "$hostname" > /etc/hostname The 'multi-distro standard' is du jour at best and imo not a compelling reason to follow. -- Daniel Campbell - Gentoo Developer OpenPGP Key: 0x1EA055D6 @ hkp://keys.gnupg.net fpr: AE03 9064 AE00 053C 270C 1DE4 6F7A 9091 1EA0 55D6
