[syslinux] Booting from various ISO files directly

[SF Markus Elfring]

Hello,

Various boot parameters can be considered in alternative GRUB 2 configurations.

I would like to clarify command line parameters like the following a bit more
for the purpose of booting ISO images better.

1. bootfrom

2. findiso

3. iso-scan/filename


Which Linux variants do support them nowadays directly?

How are the chances to specify predictable (persistent) names there instead of
“old style” device names?

Would you like to improve the support for other path specifications?

Markus
