It isn't just Audacity, I just emerged gvim and that does the same (no
text at all). Firefox OTOH is fine, as is xfontsel.

I can't see anything in the strace which indicates any fonts used,
presumably it's in the data over the X connection (strace only shows a
small amount per call).

Since everything I want is in the home directory (with the exception of
local stuff, that's what /usr/local is for), it needs to be mounted
everywhere anyway.

Yes, killing all user process -- including ones run as cron jobs --
basically means going down to at least single user state, so may as well
reboot completely (the only extra cost of that is re-fscking the local
drives).

I've never wanted a filename with : in it (scp can't handle those
either, nor can a load of other things). Bad enough that some have
spaces.

The 2GB limit (I thought it was 4GB for Samba?) is why I mentioned cifs,
which doesn't have that limit. But the bad handling of attributes and
ownership makes it less useful than NFS.

The only issue with the mixer is the broken documentstion of the ALSA
API. And that's broken documentation, not functionality...
