Jailed mysqld doesn't work after a backup

[Vincent Bolinard]

Hi,

Yesterday, I backed up my MySQL jail with "tar jcpf" (and used tar
jxpvf to extract).
Now, when I try to run it as I used to (jail -U mysql /jail/mysqld/
mysqld.domaine.com 192.168.1.6 /usr/local/libexec/mysqld &), it fails
giving me a "Permission Denied" error.

If I try to run it with "chroot -u mysql /jail/mysqld
/usr/local/libexec/mysqld &", it works !

I don't understand.

Does somebody have an idea ?

Thank you.

P.S.: I'm running FreeBSD 6.2-RELEASE and MySQL server 5.0.27.
