Thank you all fro your efforts.
Sorry but today I was out of office and I had no time to test, I'll restart testing this monday
I'll try to deal with rootdelay, but I don't think this will fix because using the device name like /dev/sde1
here you can find the relevant parts of my testbed, just to view if something is wrong
partition labels and UUIDs:
/dev/sde1: UUID="c347c1e4-e49f-4b7b-914d-b8f681c03428" TYPE="swap" LABEL="slackswap"
/dev/sde2: LABEL="slackware" UUID="8563d7da-09d8-4956-a6a4-77e2e3eb341e" TYPE="ext4"
fstab (perfectly working):
LABEL=slackswap swap swap defaults 0 0
LABEL=slackware / ext4 defaults 1 1
image = /boot/vmlinuz
# append = "root=UUID=8563d7da-09d8-4956-a6a4-77e2e3eb341e"
# append = "root=LABEL=slackware"
label = Linux_test
I tried the three commented line (only one for time) without results
Monday I will do further tests
Thank you all
