This is a draft of some sorts of ideas, future changes, and fixes for
archiso that I have in mind:
* UEFI boot support (FS#20419)
At some time I want to support UEFI boot. But I do not have any real
hardware to test it. Neither UEFI firmware for qemu (two versions
tested) or virtualbox works fine, testing with some UEFI compatible
mediums without happy results.
* syslinux keymaps (FS#21725)
I worked on this some time ago, but I want some feedback from people
that needs this, we need a trivial lilo patch for keymaps generation.
* syslinux helps
For now, put boot options that are on the new README.
Self check of all files (mostly important *.sfs), as boot option,
executed at initramfs stage. $install_dir/checksums.md5
* swap on zram (FS#18463)
A boot options that setup a zram storage for swap space. (I done some
tests with my custom build and works nice, helps a lot on machine with
512MiB of RAM). This feature will be experimental since zram is in
* dm-snapshots cow on zram
Currently *.cow files are store on a a single tmpfs filesystem
/cowspace. We can setup one zram device for each cow device directly
without any filesystem.
* cow options (cowdevice=/cowpath=)
Allow to setup a device and path where cow files will be stored, this
can be usefull for persistent feature. Live distros based on archiso can
* mount options for images based on dm-snapshot.
Allow to specify mount options in some place. Maybe in aitab (per image)
or via bootparam (global). For example for using noatime (save fews
megabytes on cow dev).
* build.sh allows execute from absolute path (implemented on my
Instead of copying all files from /usr/share/archiso/config/%blah-blah%
to some place and work on it. Allow to execute directly from
/usr/share/archiso/config/%blah-blah% and use current directory as
Needs a better error-recovery for download core repo (wget). Try again
if fails, maybe pacman can be used instead of wget (FS#18959)
* console serial port.
Needs better command line parsing, current implementation works
partially. (example console=ttyS0 does not work, needs at least speed
Feedback is welcomed, good luck!
