(In reply to comment #4) > Created attachment 337002 [details, diff] [details, diff] > complete patch RC1 It seems syslog running as user syslog isn't safe enough. Syslog should run in chroot.
chroot support in syslog-ng is useless I replaced syslog-ng with app-admin/sysklogd, which is safe enough without chroot.
