It looks like scriptlets aren't run when using a different root.
scriptlets are called by chrooting first, and then running :
execl("/bin/sh", "sh", "-c", cmdline, (char *)NULL);

Maybe this requires a proper chroot to work?


There is an additional issue in pacman git :

553     snprintf(scriptfn, PATH_MAX, "%s/.INSTALL", tmpdir);
554     /* chop off the root so we can find the tmpdir in the chroot */
555     scriptpath = scriptfn + strlen(root) - 1;
556   } else {
557     strncpy(scriptfn, installfn, PATH_MAX);
558     /* chop off the root so we can find the tmpdir in the chroot */
559     scriptpath = scriptfn + strlen(root) - 1;
560   }

If I understood correctly, root isn't a prefix anymore, so I believe that
this part is wrong now.
