Ebuilds that use cdrom.eclass must call cdrom_get_cds passing a file to look for on each CD, e.g. cdrom_get_cds cdrom_get_cds System/Packages.md5 StaticMeshes/AWHardware.usx.uz2 Extras/MayaPLE/Maya4PersonalLearningEditionEpic.exe for 3 CDs. cdrom_get_cds calls cdrom_load_next_cd and this call is successful in finding disk 1. Subsequent calls to cdrom_load_next_cd from the ebuild fail to find subsequent disks. cdrom_get_cds exports an array, CDROM_CHECKS, containing the files to look for on each CD (basically, what it was called with). It is not possible, in Bash, to export an array to the calling environment as there is no POSIX representation of storing arrays in the environment and the calling shell may not be Bash. This is why the first call to cdrom_load_next_cd works (as it is invoked from Bash), but subsequent calls from the ebuild fail (as CDROM_CHECKS is no longer defined). I have fixed this in https://github.com/gentoo/gentoo/pull/5818.
Sorry for the delay, I was without my desktop for a few weeks. I have managed to reproduce this but while I'm still unsure about the precise cause, I think your reasoning is a little off. Portage (et al) will always use Bash so we don't have to worry about other shells. The Bash version is significant though. It's guaranteed to be at least 3.2 under EAPI 5, which this package uses. Unfortunately I have UT2004 but not UT2003 so I wasn't able to try this package but I did reproduce it with games-rpg/comi by moving some of src_unpack into src_install. Initially it worked fine for me but I noticed that you have Bash 4.3 while I have 4.4. I then pointed /bin/bash to 4.3 and that did the trick. I thought that the environment file was able to faithfully represent arrays so I compared the file between the two Bash versions. 4.4 includes the following line but it is missing under 4.3. declare -ax CDROM_CHECKS='([0]="comi.la1" [1]="comi.la2")' I checked the release notes for 4.4 but couldn't find anything that seemed to relate to this. If I fire up 4.3, declare the array, source Portage's save-ebuild-env.sh script, and call __save_ebuild_env then the above line is actually included. I don't yet know why it's only missing under Portage.

It may be the case that Portage will always use Bash but Bash itself is unaware that it is being used in Portage and cannot assume anything about its calling environment (other than it being POSIX). This is a bug in the interaction between Portage and Bash - i.e. Portage is expecting Bash to have a feature it doesn't, specifically the ability to export arrays (or save/restore arrays) to the calling environment. > I checked the release notes for 4.4 but couldn't find anything that seemed to > relate to this.

I don't yet know why it's only missing under Portage. Are these functions part of Portage? Where can I find them to debug the problem further? I couldn't find anything in the Bash Changelogs either but did find this post about exporting arrays from Bash on StackOverflow: https://stackoverflow.com/questions/5564418/exporting-an-array-in-bash-script Two links from answers to that post are interesting: https://www.mail-archive.com/bug-bash@gnu.org/msg01774.html and http://www.openwall.com/lists/oss-security/2014/09/30/1. Particularly the author states that exporting arrays is incomplete in 4.3 and has no plans to complete that part of the code. Maybe it has been completed in 4.4 but 4.3 is latest version of Bash available in the stable amd64 arch. From one of the answers: "The first thing to understand is that the bash environment (more properly command execution environment) is different to the POSIX concept of an environment. The POSIX environment is a collection of un-typed name=value pairs, and can be passed from a process to its children in various ways (effectively a limited form of IPC)."
