ad-n770hi, I'm running an Intel skylake system with Ubuntu 15.10 + kernel 4.4rc7 installed from mainline ppa http://linuxdaddy.com/blog/install-kernel-4-4-on-ubuntu/18:43
ad-n770I'm facing some strange issue with schroot18:44
ad-n770unkown filesystem type 'overlayfs'18:44
ad-n770during the mount stage18:44
ad-n770I've checked with the stock kernel 4.2 and it works, so it must be somehow tied to 4.4 kernels18:45
ad-n770could you provide me some hints?18:46
ad-n770I've also tried with rc5 and rc6 with same results18:47
ad-n770with lsmod | grep overlay seems that module isn't loaded18:49
ad-n770cat /proc/filesystems | grep overlay same18:49
ad-n770modprobe overlay seems to load the module18:50
ad-n770but I'm still getting the mount problem with schroot18:51
ad-n770with cat /proc/filesystems | grep overlay I'm only getting overlay and not overlayfs after modprobe overlay18:54
ad-n770also reproducible with 4.3.3 kernel from ppa19:08
simosxad-n770, I think there has been a renaming for the kernel module, between overlayfs and overlay. The scripts should work, as "overlayfs" is an alias for "overlay". However, it's possible that somewhere this aliasing may not work. 20:07
ad-n770you were right, at the end I've just needed to change my schroot file at /etc/schroot/chroot.d/20:27
apwad-n770, yes you are trying to use the "compatible with older kernels" overlayfs, if you don't have V1 suport you have to use V2 (overlay)20:54
