But currently none of the expected ways work as non-root:
$ mmdebstrap --mode=root --variant=required --keyring=/usr/share/keyrings/debian-ports-archive-keyring.gpg '' foo.tar.gz 'deb http://deb.debian.org/debian-ports unreleased main' 'deb http://deb.debian.org/debian-ports/ unstable main'
E: need to be root
with additionnal fakeroot-hurd:
$ fakeroot-hurd mmdebstrap --mode=root --variant=required --keyring=/usr/share/keyrings/debian-ports-archive-keyring.gpg '' foo.tar.gz 'deb http://deb.debian.org/debian-ports unreleased main' 'deb http://deb.debian.org/debian-ports/ unstable main'
Undefined subroutine &main::SYS_capget called at /usr/bin/mmdebstrap line 6081.
/bin/fakeauth: Error 255 for child 23498
/bin/settrans: Error 255 for child 23497
$ mmdebstrap --mode=fakeroot --variant=required --keyring=/usr/share/keyrings/debian-ports-archive-keyring.gpg '' foo.tar.gz 'deb http://deb.debian.org/debian-ports unreleased main' 'deb http://deb.debian.org/debian-ports/ unstable main'
E: need working fakechroot binary
on GNU/Hurd it should be using chroot instead of using the fragile
fakechroot. I had tried to create a hurdish fakechroot that just calls
chroot(), but apparently mmdebstrap is expecting various fakechroot
environment variables, I didn't easily manage to find out what.
