[Bug 1915515] Re: "toram" loads the entire media, not just filesystem.squashfs

2021-03-11 Thread Dark Penguin
Oooh, I never thought about this use case!.. I thought it's just for
convenience: you can get an ultra-fast system instead of really slow
USB, and you don't have to worry about accidentally mixing up the drives
and nuking your flash.

My current use case is: make a multi-boot USB as a sysadmin tool for
rescue, bug testing and distro testing. Removing the flash after boot is
convenient if I work on several computers at the same time, and things
being really fast helps too. Reducing the memory requirements would
help, and removing the need to repack filesystem.squashfs into an ISO
would help greatly.

I would suggest having "toram" keep the existing functionality, but
adding "toram=filesystem.squashfs" that acts the same way as in Debian
(loads only the specified file). However, this would probably be a
significant pain to implement, for a moderate benefit in a pretty exotic
use case. Unless more people want it for whatever they are doing.

[Bug 1915515] Re: "toram" loads the entire media, not just filesystem.squashfs

toram is meant to be the option for single disk devices.

I.e. when iso is blasted on the drive. machine is booted off that drive.
installer is transfered to ram. and then installation is done on the
same drive.

Unless we transfer all of ISO to ram, this will not be possible to
complete correctly, or at all if there is no network connectivity.
