I'm looking at trying to speed up my boot time on the x86 system. I've noticed a few seconds seem to be wasted around trying to mount some file systems.
[ 3.340045] usb 1-4.1: new full-speed USB device number 4 using xhci_hcd
[ 6.042272] urandom_read: 5 callbacks suppressed
[ 6.042275] random: jshn: uninitialized urandom read (4 bytes read)
[ 6.097986] mount_root: loading kmods from internal overlay

[ 6.853895] random: jshn: uninitialized urandom read (4 bytes read)
[ 7.277882] procd: - ubus -
Particularly odd were the two entries of
[ 7.186295] block: attempting to load /etc/config/fstab
[ 7.192393] block: unable to load configuration (fstab: Entry not found)
Any idea what is causing this?
