@pid_eins@mastodon.social yes I was joking about the speed. 3gb. I think having dm-verity on a separate partition might slow it. Also running ldconfig is a bad idea. I could do some more testing but I do not know how important this is.

@Valentin@mastodon.social @pid_eins@mastodon.social If ldconfig is running, that means that /usr timestamp was not set up properly. It should not run after a clean install.

@Valentin@mastodon.social my guess is that seek times kill you. I think cdroms/dvds have random seek times of 200ms or even more on old drives, which is abysmal. If you actually care about this you could start reading linearly into memory. On a dvd that's like 1.5mb/s though, i.e. also pretty awful... I.e. 90mb/min. So for 3gb it's too slow. What people used to do is profile what is actually accessed during boot and then put this stuff at the beginning of the medium, and read that in linearly.
