tinc running openwrt (mikrotik metarouter mips)

this indicates that your sources file (/etc/opkg.conf) pointed to a more recent
release of openwrt than the one that you installed.
The proper action at this moment would have been to change the repository
source urls in /etc/opkg.conf to a matching release.

As far as I understand openwrt, this is something that just will not work.
Every installed package will end up in the "overlay" filesystem. This special
filesystem is not active during bootup - thus you cannot boot the fresh kernel.

"Upgrading" an openwrt system by installing new packages is usually not possible
due to the compressed read-only filesystem (squashfs) which is used for booting.
A "sysupgrade" with a new image is the proper way to go.
