@ -4,6 +4,18 @@ This is a simple shell script to build a live image for the
|
|||
Void linux distribution. The images contain the void-installer package
|
||||
to be able to install Void linux to storage disks.
|
||||
|
||||
The generated image can be booted from BIOS and EFI systems (dual boot).
|
||||
For BIOS isolinux is used and for EFI we use grub2.
|
||||
|
||||
Dependencies:
|
||||
- dracut
|
||||
- grub with support for PC-BIOS and x86_64 EFI
|
||||
- syslinux
|
||||
- dosfstools (for mkfs.vfat)
|
||||
- xorriso
|
||||
- squashfs-tools
|
||||
- void-installer
|
||||
|
