I have a couple of slugs both running debian arm and am now very much
aware of the fact that squeeze has dropped arm from the distributions in
favor of armel. The only migration procedure that I have discovered so
far is the one on the ArmEabiHowto, e.g. the section "Migrating arm
installation to arm EABI installation". Althought the procedure is more
of a "re-install" approach, which is okay I suppose, the rough point in
the procedure is step 6 where it says:
6 boot into single user mode and make sure there is no processess running
So far, I not found a clear description of that step.
