Am observat ca problema de mai sus a fost rezolvata, insa se pare ca acum
pica testul 4:
vmchecker storer: Running tests ...

Total: [099/100]
E posibil ca /dev/tracer sa fie deja creat in sistem cu permisiuni inaccesibile.
Am observat ca problema asta apare la mai multe persoane care au trimis tema.
Multumesc,
