    /usr/local/cpanel/bin/jailmount appears to be missing mounting the files in /etc for the user's chroot.

    Code:
    # ls -al /home/virtfs/chroot2w/etc
    /bin/ls: cannot access /home/virtfs/chroot2w/etc: No such file or directory
    # /usr/local/cpanel/bin/jailmount chroot2w
    # ls -al /home/virtfs/chroot2w/etc
    total 24
    drwxr-xr-x  6 root root 4096 Oct 26 12:45 ./
    drwx--x--x 13 root root 4096 Oct 26 12:45 ../
    drwxr-xr-x  2 root root 4096 May 26 00:04 alternatives/
    drwxr-xr-x 11 root root 4096 Oct 20 10:16 apache2/
    drwxr-xr-x  3 root root 4096 Feb 25  2014 mail/
    drwxr-xr-x  3 root root 4096 Oct 26 12:45 pki/
    This would seem to be an issue with PHP-FPM using chroot - (touch /var/cpanel/feature_toggles/apachefpmjail - Enhance FPM support)

    If you change the user's shell to jailshell and change into that user, then /etc gets populated as it should:

    Code:
    # usermod -s /usr/local/cpanel/bin/jailshell chroot2w
    # su - chroot2w
    Attempting to create directory /home/chroot2w/perl5
    [~]# exit
    logout
    # ls -al /home/virtfs/chroot2w/etc
    total 1240
    drwxr-xr-x 13 root root       4096 Oct 26 12:51 ./
    drwx--x--x 14 root chroot2w   4096 Oct 26 12:51 ../
    -rw-r--r--  1 root root       1624 Feb 26  2014 aliases
    drwxr-xr-x  2 root root       4096 May 26 00:04 alternatives/
    -rw-r--r--  1 root root      10634 Jul  6 10:04 antivirus.exim
