I just came across some problems when using chrooted cron jobs for clients. The feature itself works without problems, but there are a lot of libraries missing if you try to use php commandline cron jobs. On jk_chroot creation the php binaries are copied over but no php.ini from /etc/php5/* No libraries from /usr/lib/php5/<zendversion>/*.so No dependency libraries for the above php modules. No pear/pecl files. The most important issue with that is that mysql, gd and curl usage are not working and there seems to be a big problem with date and time functions due to missing timezones database. I think this renders php cli useless on chrootet cron, what do you think?
