Problems with chrooted Apache and PHP exec() function

[Johan L]

Hi,

We are trying to get the PHP exec() function to work in a chrooted 
Apache environment (4.1-stable MP ACPI enabled, PHP 5.1.6).

Even if using a static binary (for example date) in the chrooted 
directory, exec just returns 127.

Everything works fine when running chroot from the command line, eg:
chroot -u www -g www /var/www date

If we start Apache without chroot (-u) then it works too.

Any suggestion on how to solve this (other than disabling chroot of 
course...)?
