Things get easier if you follow that simple and easy fact to not mess around with files in sys:morphos/.
Sure an old Amigan feels like he knows the system and isn't afraid to tinker around, but there is a good reason for that rule.
That's not a "fact", just a general rule.
Unfortunatly, in many cases you _have_ to mess around in sys:morphos - with 2.5 this has changed somewhat, since now more paths under sys: is also read automatically, read all about it in the update notes. Still, you have a library you want to use rather than the one in mossys:, updated mui classes, rexxsyslib.library or whatever - you quickly end up needing to change stuff in mossys:. Not that I mind, most of the time I seem to have a clue on what I'm doing, since I have yet to break any systems.
And yes, I have altered the startup-sequence, removed all unneeded occuarances of >NIL:, lowered the failat value (rexxmast always exits 11 on morphos for some weird reason), shuffled around assigns, made my own c:mount wrapper that unmounts devices that are to be mounted but already exists (such as con), removed the resident lines for execute and assign (set the H flag on them instead), altered PATH, removed all the turboprint stuff I couldnt care less about, ditto for SDK etc.
I mean - this is why I would want an amiga system in the first place - I can tinker around with it as I am pleased, because it's a kind of system I know how to mess around with. :hammer:
