mod_perl and chroot

[James Breat <ko...@hotmail.com>]

Hi,

I am trying to get mod_perl to work in chroot using mod_chroot. It works fine without chroot.
This is the error am getting:

"failed
to resolve handler `ModPerl::Registry': Can't locate
ModPerl/Registry.pm in @INC (@INC contains:
/usr/lib/perl5/5.8.8/i486-linux-thread-multi /usr/lib/perl5/5.8.8
/usr/lib/perl5/site_perl/5.8.8/i486-linux-thread-multi
/usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl .
/usr/local/srv/apache2) at (eval 2) line 3.\n"

locate Registry.pm returns:
/usr/lib/perl5/site_perl/5.8.8/i486-linux-thread-multi/ModPerl/Registry.pm

strace
reports:
stat64("/usr/lib/perl5/site_perl/5.8.8/i486-linux-thread-multi/ModPerl/Registry.pm",
0xbfbf20ac) = -1 ENOENT (No such file or directory)

I know php_mod works fine with mod_chroot without having to copy any libs into the jail, is mod_perl different?

Thanks.

James

I don't think that is true for your new root. So either copy all needed 
modules to it or load them *before* the chroot call. AFAIK mod_chroot 
installs a PostConfig handler at APR_HOOK_REALLY_LAST+10, that means 
really_really_last. Anything before that runs in the original root and hence 
can load modules, see
