Bug 692952 – emergeing binary from different prefix or an arm64 chroot fails

• Product: Gentoo/Alt
• Status: RESOLVED OBSOLETE

[Description devfx11 2019-08-27 13:49:27 UTC]

Trying to emerge a tbz2 file from a different prefix or a arm64 chroot
emerge -avK htop for examples gives this result 

These are the packages that would be merged, in order:

Calculating dependencies... done!
[binary  N     ] sys-process/htop-2.2.0::gentoo  USE="unicode -openvz -vserver" 0 KiB

Total: 1 package (1 new, 1 binary), Size of downloads: 0 KiB

Would you like to merge these packages? [Yes/No]

There is no such file : /data/gentoo64/var/tmp/portage/sys-process/htop-2.2.0/image
The directory is there while >>> Adjusting Prefix to /data/gentoo64
After that finishes it gets renamed to image_tmp
And then the failure.

I first had issues with gcc. Gcc is a larger package and i had time to look around the directory to see image directory being there while Adjusting Prefix to /data/gentoo64.

Reproducible: Always

Prefix adjusting is brittle and surely mixing between prefix and non-prefix isn't going to work
