Re: [systemd-devel] stacked extension not working
Thanks and I would have never figured it out without your help. However, moving the binary to /opt didn't work either (I made sure there is empty /opt in the base too).

[systemd-devel] stacked extension not working
Hi, following works for us (for reference, configuration is printed at the end) portablectl --now attach --extension=./stackupper ./base stackupper However, if we move the cat from base/usr/bin/cat to stackupper/bin/cat it is not working. Seems like we cannot include any library/executable in the extension.
