tomoyo-tools (2.6.0-20201111-1) unstable; urgency=medium Since tomoyo-tools 2.6, it needs Linux 5.1 and above, if you run it with older Linux kernel then gets panic. -- Hideki Yamane Sun, 24 Jan 2021 00:54:30 +0900 tomoyo-tools (2.4.0-20111025-1) unstable; urgency=low tomoyo-tools version 2.4 is not backward compatible with previous version. As same as 2.3, it will backup the old database under /etc and re-initialize with a new database. -- Hideki Yamane Sat, 10 Dec 2011 20:28:07 +0900 tomoyo-tools (2.3.0-20100820-1) unstable; urgency=low tomoyo-tools version 2.3 is not backward compatible with 2.2's database. Upon installation, it will backup the old database under /etc and re-initialize with a new database. In case the old database is still used with the 2.3 release, the linux kernel will panic at boot time. You can workaround the problem by booting with 'security=none' and removing the /etc/tomoyo/* files and then running /usr/lib/tomoyo/init_policy The 2.3 version also depends on Linux kernels 2.6.36 and above for many of its new features. -- Ritesh Raj Sarraf Sun, 13 Feb 2011 23:11:41 +0530
