make install[kernel|world] from read only /usr/obj possible ?
Date: Tue, 24 May 2022 18:58:44 UTC
On RELENG_12, I was able to mount via NFS /usr/obj and src and do an
installworld on read only mounts. However, with RELENG_13 and above, I
get permission denied errors. The install seems to continue just fine,
but I am not sure if something subtle is being missed. Looking at what
gets installed, the kernel modules get installed just fine. However, it
seems installworld has some problems with static libs (.a files). They
dont seem to get re-installed. However, not sure if thats by design as
doing a quick checksum, there is no difference on the build server and
target of the ~ 700 .a files I checked in /usr/lib32 and /usr/lib. So
despite the time stamps being off, maybe it just does not bother to
update the target if they have not changed?
e.g.
make KERNCONF=vtnet installkernel

Looking at the pcap, nothing stands out as to what the problem might be.
Looking at the replies, the ERROR is just "ERROR: No such file or
directory" and doesnt correlate to the permission denied errors
