>> ERROR unshare (Operation not permitted)
This is the actual error: unshare does not have setgid (or you are not
in the group).
I believe the error is actually related to running xbps-src inside a Docker container, as setting setgid, or running as root make no difference. For the record, after much trial-and-error I have managed to find a combination that works. It required running the container as user root, and with both the --privileged and --cap-add=SYS_ADMIN options.
However I have not entirely given up on finding a simpler solution. One promising route seemed to be to use the proot utility, which works in userspace, thus potentially avoiding all these permission problems. However when I try building using proot I see the following:
> configure: creating ./config.status
> config.status: creating MakefileI the following:
> mv: cannot move './confT6XesZ/out' to 'Makefile': No such file or directory
> config.status: error: could not create Makefileerrors
I've had a bit of a go at reverse engineering the xbps-src build process, but found it all a bit confusing, so wondering if anyone might have seen something like this before.
Thanks as always.
