Thank you for this report and the idea. I have two immediate problems with it: 1. I chose Sunday specifically so as to not interrupt work (which may well be a false assumption anyway). However, the new --idle command line option will probably alleviate this anyway. 2. Your solution works, and it's exactly what the (useless) /usr/bin/hostid should do. I am a little sceptical about using a non-standard approach for this. Anyway, I am leaving it open for comments and consideration. -- .''`. martin f. krafft <[email protected]> Related projects: : :' : proud Debian developer http://debiansystem.info `. `'` http://people.debian.org/~madduck http://vcs-pkg.org `- Debian - when you have better things to do than fixing systems
