Unify the syslinux directory & config file name between ISO and installed USB stick
In the ISO we ship an isolinux directory that contains an
isolinux.cfg file. And then the USB installers (ours and various 3rd
party ones used e.g. on Windows) have to rename isolinux → syslinux,
isolinux.cfg → syslinux.cfg, and to adjust the config files accordingly.
I’m
told
that isolinux.bin would read that file just as well if it was called
syslinux.cfg, and we can give the (currently) isolinux directory
whatever name we want, as long as we tell xorriso where it is.
So it seems that we could ship a syslinux directory in the ISO, with a
syslinux.cfg file in it. Then it’s probably a matter of ensuring we
pass the correct -b option to XORRISO_OPTIONS so live-build’s
lb_binary_iso does the right thing.
This would allow all USB installers to drop quite a bit of code, and
would bring us one step closer to having “intermediary” Tails sticks
look more similar to those installed with Tails Installer. I also expect
it would help ensure that 3rd party USB installers do the right thing,
and they would simply have nothing to do except running our embedded
syslinux to have ldlinux.sys installed.
