Re: [PATCH] Core Update 169: Regenerate initrds and save space on ARM

Hello,

Indeed we don’t need to ship them, we can generate them instead.

But that has of course some downsides, too:

* It is slow
* It is not entirely error-proof (out of disk space, out of memory, system being rebooted too early)

I do not really have much of a preference. The only thing I want to say is that ARM needs to get their shit together and being able to load a regular image instead of asking for extra commands here - or build that into dracut.
