Im running sid now sucessfully for a couple oft years. The last update on 4.8. gives me some headaches, though.
After the upgrade Boot falls with multiple errors, a common part is
trap divide error ip:7f88f70e601b sp:7fffde9ce760 error:0 in libc-2.17.so[7f88f70b9000+1a2000]
I can however Boot when I set init=/bin/bash in the kernel command line.
I was suspecting the libc upgrade to 2.17-92 so I downgraded to 2.17-7 (testing) but to no avail.
Note: I was using apparmor but habe removed it now.
Note: I am using systemd
