4Subject: [PATCH] When cross-installing, execute package scriptlets without
5 chrooting into destination rootfs
6
7This is triggered only when RPM_NO_CHROOT_FOR_SCRIPTS environment variable is defined.
8Otherwise they will trigger an explosion of failures, obviously.

10Amended 2018-07-03 by Olof Johansson <olofjn@axis.com>:
11
12  Remove leaking temporary scriptlet files
13
14  Since we tell dnf to run rpm with debug output, this will result in rpm not
15  cleaning up written temporary scriptlet files (same flag controls both
16  behaviors). This wouldn't have been a problem since we normally would use the
17  target sysroot also for temporary files, but we need to chroot out to be able
18  to actually run the rpm scriptlets (purpose of this patch), so the temporary
19  files are written to the host's /var/tmp/ directory, causing a gradual
20  resource leakage on the host system for every RPM based do_rootfs task
21  executed.
