# Patch upstream archinstall in place for two Python 3.14 / archinstall 4.3
# bugs that hit our flow:
#
# 1. logfile_target join: '/' on an absolute Path with another absolute Path
#    raises. Strip leading slash so the join produces target / "var/log/..."
#    instead of throwing.
#
# 2. Limine EFI copy: archinstall passes the destination directory but limine
#    .copy() expects the destination file path. Two sites: limine_x64.efi
#    copy and limine-bios.sys copy.
#
# Idempotent: re-running is a no-op (sed only matches the buggy form). Carry
# this until upstream Arch's packaged archinstall has the fixes.
