<div dir="ltr">Hi again. I tried renaming (<a href="https://www.freedesktop.org/software/systemd/man/os-release.html">https://www.freedesktop.org/software/systemd/man/os-release.html</a>) it but that didn't work. I am not getting any errors during the attachment phase so I am not sure if the failure is due to extension file in any way. <div> </div><div>A wish list is to be more verbose regarding what is going on during extension file check/comparison and during overlaying /usr and /opt. I think portablectl is quite verbose when it comes to preparing files, symb links and what I wish fits well. <div> </div><div>Could you please try it yourself?

This too is documented in the man page. > On Fri, Oct 15, 2021 at 2:23 PM Luca Boccassi <<a href="mailto:bluca@debian.org" target="_blank">bluca@debian.org</a>> > wrote: > > On Fri, 2021-10-15 at 12:18 +0000, Umut Tezduyar Lindskog wrote: > > > 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.
