South Americans have done much for the free software...Ututo,
Dragora..Kongoni...Canaimix...
Hyperbola, Parabola too, if I am not mistaken. I know of at least one person that liked
using hyperbola on LibreBoot but I didn't convince him enough to try Adelie. I've
been a fan of Adelie for a while, beta1 I think (Fall '18), and I am still here. I
think it is worth the trouble to borrow a different machine, make an installation of the
base system, then use dd and copy the partition image to a disk and transfer it to your
libre boot (run configure grub/syslinux again on the new host).
To Adelie team: Maybe a tarball of the base system, no kernel, should also be available
for someone experiencing boot problems, so one can chroot and setup an installation on
their own.
PS The last image I tried worked for me in bios machines.
