I did the same exercise last week, doing a full install on the
'spare' system of the Casa del Suono, the one that should be
able to take the place of any of the 5 machines used there if
any one should break.

Had some booting problems (solved by blacklisting the pata_acpi
module) but otherwise everything seems to work. 

One thing I still have to investigate is that contrary to what
logind is expected to do, audio devices are still owned by user
root, group audio - exactly as I want things to be. According
to the docs logind would assign them to the login of the 'active
session' instead. 

Another thing I noticed is that if there is some error condition
during boot, and then doing a powerof, systemd seems to do an 
'alsactl store' even if didn't yet reach the 'alsactl restore'
during booting. The result is that your defaults are overwritten,
e.g. for an RME MADI the stored state will have all gains at zero.



A world of exhaustive, reliable metadata would be an utopia.

and hysterically inflated market opportunities. (Cory Doctorow)
