[9fans] Q:How to replace 9load in the 9fat partition?

[icQQ]

I have done some changes on 9load source and recompiled it.
I read `Notes on Plan 9 source' and it says 9load is stored
continuously on the 9fat patition, can i replace it with new
version directly, or how to replace in another way?

Thanks

the mode of the file on 9fat is set specially (see dossrv(4)),
and provided the bits remain set, you can just
	cp new9load /n/9fat/9load
and it should be fine.  you can also chmod +al /n/9fat/9load
later if the bits aren't set.

If it's not significantly bigger than before, just cp it.  If its
permission bits change, you need to use disk/format as shown in man
prep, with all the pertinent provisos.

this isn't true.  as forsyth said, all you have to do
is chmod +al it if the permission bits change.
if chmod fails, then you might need to do some
moving things around to make some contiguous
disk space.
