In the past I have used the VC2 shell to swapon immediately the
partitioner has formatted the partitions (but not swap), ie just
before "Install the base system". This has never caused a problem
for me, but the Installation Guide says:

"In particular, you should always use [sic] let the installer activate
your swap partition and not do this yourself from a shell." (§6.3.8.2)

Any idea why?
