Bug #1518

CD/DVD long boot time / unclear log

Description

The CD/DVD uses mount_mfs to create a writable directory structure. Unfortunately mount_mfs copies all overlayed files instantaneously, leading to a very long boot time.

Additionally, the mounts happen after fsck prints some error about /dev/cd0a, so one could get the impression that the system is somehow fsck'ing the CD.

Hi,

Measured with a SATA DVD drive using a normal CD. Boot time: 1 minute 57 secs.

Cheers,
Antonio Huete

Is trying to improve it really worth the effort? ISOs are mostly used for
VMs it seems and most people use our USB images.
