Yes, I am aware of this - I didn't mention it but I probably should
have said that I feel the only realistic solution to the ftp problem
(whatever path mechanism you have) is to use dbAsciiExpand. Having
accepted this, any worry about efficiencies in path mechanisms
disappears.
Having said this, I am also leaning towards having UAE encourage users
to create an ascii equivalent of default.dctsdr (i.e. by default
expanding all.ascii) no matter whether they use nfs or ftp, and using
the expanded file wherever default.dctsdr has been used in the past.
(e.g. the expanded file would be used by medm and Capfast and loaded
separately on vxWorks). This would avoid unexpected efficiency problems
and is very similar to current working practices so would probably be
accepted easily. After all record, device and driver support get
changed far less frequently than the record definitions so why do all
those rebuilds?
