Hi !
i have compiled squid-2.3STABLE5 under RH 7.1 and created a chroot-jail in
/chroot/squid with the files listed at the end of this message.
In /chroot/squid/etc/squid/squid.conf
i modified the tags like:
cache_effective_user / group squid
icon_directory chroot/squid/etc/squid/icons
error_directory /chroot/squid/etc/squid/errors
pid_filename /chroot/squid/var/log/squid/squid.pid
chroot /chroot/squid

I build the /cache directory successfully without the chroot-tag enabled.
When I start squid WITHOUT the "chroot" tag in squid.conf
# /chroot/squid/usr/sbin/squid -sYDX -f /chroot/squid/etc/squid/squid.conf
the daemon starts successfully.

When I start squid WITH the "chroot" tag in squid.conf
the parent starts but every child is killed with
Aug 29 08:46:14 wsiv-686-6 squid[1036]: errorTryLoadText:
'/chroot/squid/etc/squid/errors/ERR_READ_TIMEOUT': (2) No such file or
directory
Aug 29 08:46:14 wsiv-686-6 squid[1036]: errorTryLoadText:
'/usr/local/squid/etc/errors/ERR_READ_TIMEOUT': (2) No such file or
directory
After serveral killed childs the parent dies too.

Yes I know, it looks like a permisson problem but a

#  su squid
# cat /chroot/squid/etc/squid/errors/ERR_READ_TIMEOUT

works !

I also moved the "errors"-directory to an other places like /x or /chroot/x
and gave 0777 and rwxrwxrwx rights. Same error.

Any hints ??
