Hi everybody
Well, the last few nights I tried to get uml with humfs to run. But it
didn't work. Now I want to know if somebody else get humfs to work or is
it not ready to use?
I really need your help. What did I wrong...
Thanks in advance for your answers,
Benjamin Schmidt
Following steps did I made:
- ---------------------------------------------------------------------
$ sudo addgroup uml
$ sudo adduser --disable-password --ingroup uml uml001
$ sudo humfsify uml001 uml 500G
du: cannot access `data': No such file or directory
$ sudo su uml001
$ ./linux rootfstype=humfs rootflags=/var/lib/user-mode-linux/uml001/
