Alan sees the same problem on bare metal booting from a USB stick. At first glance, the service that waits for /dev/loop0 times out after 180 seconds, and the live-config service takes ages to start as well. The latter matches what I see in the Journal anonym shared, in which the blocking (“foreground”) part of the readahead process takes not less than 4 minutes and reads about 1.2 GiB. I’ll check what makes this set of files so big.

This is a regression, and I’m told many users believe Tails 3.3 is broken and won’t boot, while they “just” need to wait N minutes longer than usual.

• File readahead-list-Tails-3.2 added

Tails 3.3’s source:config/binary_rootfs/squashfs.sort contains lib/live/mount/medium/live/filesystem.squashfs, which easily explains why we’re reading ahead this crazy amount of data. I think source:auto/config should filter out ^lib/live/mount/medium/ when it generates the readahead list from the SquashFS sort file.

Looks better with an ISO built from the topic branch!

In libvirt/QEMU:

root@amnesia:~# head -n2 /var/log/live/config.log 
live-config: readahead
79.5MiB 0:00:03 [21.6MiB/s] [================================>] 100%  

And on bare metal + USB, it takes 4-5 seconds and the boot feels soooo much faster that I did not bother measuring it nor testing on DVD. I certainly wouldn’t mind if you did while reviewing though :)

Done, DVD boot is “fast” again! Code looks good => merged!
