# hyperbola-bootstrap: Bootstrap a base Hyperbola GNU+Linux-libre system using any GNU distribution.
|
|
#
|
|
# Dependencies: bash >= 4, coreutils, wget, sed, gawk, tar, gzip, chroot, xz, zstd.
|
|
# Project: https://git.sr.ht/~heckyel/hyperbola-bootstrap
|
|
#
|
|
# Usage:
|
|
#
|
|
# # ./hyper-bootstrap.sh destination
|
|
# # ./hyper-bootstrap.sh -a x86_64 -r https://repo.hyperbola.info:50011/gnu-plus-linux-libre/testing destination-64
|
|
#
|
|
# Example:
|
|
#
|
|
# # ./hyper-bootstrap.sh -a x86_64 -r "https://mirror.fsf.org/hyperbola/gnu-plus-linux-libre/testing" myhyper
|
|
# # ./hyper-bootstrap.sh myhyper
|
|
#
|
|
# And then you can chroot to the destination directory (user: root, password: root):
|
|
#
|
|
# # chroot destination
|
|
#
|
|
# Note that some packages require some system directories to be mounted. Some of the commands you can try:
|
|
#
|
|
# # mount --bind /proc myhyper/proc
|
|
# # mount --bind /sys myhyper/sys
|
|
# # mount --bind /dev myhyper/dev
|
|
# # mount --bind /dev/pts myhyper/dev/pts
