I think that ought to be documented somewhere in LFS. Googling for this, all that came up was a recommendation from Arch to pass loglevel=4 [ they actually recommend 3 ] among the boot arguments. Also, I haven't ever needed to use sysctl in the past - it appears to be something that is set at runtime, so if I had needed it I would have put it in an initscript. If I do this with systemd, how am I _supposed_ to do it ? [ google is not helpful, or I've got the wrong search args ]. ĸen -- das eine Mal als Tragödie, dieses Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
