In most cases it's guaranteed to _NOT_ work and render your system unusable= =20 because the UFS2 filesystem (which is the default in the 5.x branch) is not= =20 supported under 4.x.

Is there > some kind of tutorial for this? Yes, it's possible, however for most users the easyest and safest way is to= =20 backup valueable data, and do a fresh install. This way you can take=20 advantage of all the features of the new filesystem. If you must do a sourc= e=20 update for some reason, the upgrade process is described in detail in=20 src/UPDATING. > > Thanks, > P. cheers, m. =2D-=20 Marton Kenyeres - mkenyeres@konvergencia.hu KVG Konvergencia Kft.
