I cannot eject or mount the drive in LiveSlak Toram for masochists.

Hello everyone, how are you?

I like portable linux systems, I have been using Porteus Linux for a while and it is wonderful, I just copy the whole live into RAM, use or eject the USB when I want. I found out that LiveSlak can also do the same:

But it didn't work the way I want. The error is that despite copying the live into RAM and returning the message "You can now safely remove the live medium." the device cannot be mounted or ejected, unless I unplug the USB and plug it back in then it works normally, but it doesn't make sense to me, as it is awkward and doesn't happen to me in Porteus Linux. /dev/sdb is my USB drive:

I am using a custom variant consisting of a Slackware with all the modules you can see there. where is the problem?

Maybe post this on Eric's blog in comments.

I don't see how you could unmount the LiveSlak usb, because you have loop mounted all the sxz files, and with the drive out they go AWOL. You also have sdb3 mounted on /, so that's going to be problematic also. Now theoretically you might find ways around those issues, but I'd get a better idea.
