Used CTM to update my 3.4 machine so that I would have the
latest picobsd sources. CTM did not appear to set execute
permissions in the picobsd tree.

Appears that I can not trust file permissions from CTM.

Is this true ?

Make world worked fine and new kernel worked.

Restored execute permissions by hand in picobsd tree, but
pico kernel would not build any more after CTM, complaining
could not find .o files. seems like looking for .o files in
same direcory as respective source files.

Handbook and Lehey book give CTM invocation example as
ctm -v -v (ctm directory)
don't they mean ctm -u -v instead ?

CTM would be my update method of choice if I can trust it.

thanks

What execute permissions? Only directories need them (and i've never
seen a problem with them when i was using CTM), files are just mode
644 or 664.

I think you did something fundamentally wrong, but your description is
not enough to see what.

Quote:> CTM would be my update method of choice if I can trust it.

The only problem with CTM is that it has no implied method of checking
data authenticity (i. e. somebody could fake you a CTM delta stream
which is internally consistent, if he's always sitting in the mail
flow between the CTM source and your site). Data integrity is
maintained pretty well in CTM.

Never trust an operating system you don't have sources for. ;-)
