After "fdisk -l" to validate that my booting drive is in fact /dev/sda mount /dev/sda8 /0/sa08 because I want to work in partition 8 What I get in response is ========================================================== # mount /dev/sda7 /0/sa07 mount: /0/sa07: /dev/sda7 already mounted or mount point busy. dmesg(1) may have more information after failed mount system call. ========================================================== Why is TW not letting me mount by confirmed device-name? It seem to me that I once removed some package that fixed the issue but I don't remember what that package was, and now it's back to square one. Any other fix? I used disk-labels for a while too but got into trouble with those being used together with uuids :-(
