Also, I verfied that `systemd-nspawn -i $IMAGE` with such a disk image fails on stretch/v232 and on jessie-backports/v230. It works on jessie/v215. I just tried to build systemd v232 with the commit applied on top, but it does not compile because it's missing the type 'MountSettingsMask'. I have not looked into that any further. > Regards, > Michael > Thanks, Felix build-ro-disk-image.sh Description: application/shellscript
