Hi,
This seems a common question, but it is a bit different.
Production OS: FreeBSD 6.2
Source OS: FreeBSD 7.2
I created a jailed mysql 5.1 in my source OS FreeBSD 7.2, and then tar
it up and scp into a production OS FreeBSD 6.2.
After setup a jail in 6.2 for the jailed mysql, I tried to start up
mysql server, but it failed with very lilttle error message.
The error log just said,
"
090525 20:18:26 mysqld_safe Starting mysqld daemon with databases from
/usr/local/var/db/mysql
090525 20:18:26 mysqld_safe mysqld from pid file
/usr/local/var/db/mysql/wp1.xxx.au.pid ended
..
"
What is the problem with Freebsd 6.2 running 7.2 jailed files?
Is there anyone to fix this problem?
It is problem with versions of linked libraries"

As you can see, there is different libc.so version, different threading
library, etc.
So you can't run MySQL daemon build on different major version OS.
