Package: openssh-server
Version: 1:4.6p1-5
Severity: normal
--- Please enter the report below this line. ---
sshd executed in chroot-environment refuses connections if SELinux is
disabled by boot option selinux=0, whereas with sshd executed in
"regular" environment same ssh-login works flawless.
chroot-environment is built "manually" using cdebootstrap and strace,
I tried hardly to append all files used by sshd.
