CONFIG_NETWORK_FILESYSTEMS not set in /proc/config.gz

CONFIG_NETWORK_FILESYSTEMS not set in /proc/config.gz

[K. Ernel]

hello list,

I usually switch to a new kernel version using the
old .config file by doing:

    # zcat /proc/config.gz > .config
    # make oldconfig

however, with the last two (or so) versions, I always lost the network
file system configuration. It's not present in config.gz,
while in the old .config of the previous release, it _is_
present, plus I'm abble to use network file system support
in the current (before the update) kernel.

e.g.:

(1) kernel version:
    # uname -r
    2.6.25.9

(2) this kernel version's configuration in the sources:
    # grep NETWORK_FILE linux-2.6.25.9/.config
    CONFIG_NETWORK_FILESYSTEMS=y

(3) this kernel version's configuration in /proc/config.gz
    # zcat /proc/config.gz | grep NETWORK_FILE
    # CONFIG_NETWORK_FILESYSTEMS is not set

(4) to proof this kernel version has indeed network filesystem:
    # lsmod| grep nfs
    nfs                    86896  1 
    lockd                  38280  2 nfs
    nfs_acl                 1792  1 nfs
    sunrpc                101884  10 nfs,lockd,nfs_acl


to me, this looks like "CONFIG_NETWORK_FILESYSTEMS" is "forgotten" in
config.gz, but what do I know ...

please fix if possible,
thanks,

Hi,

I can't reproduce it on 2.6.25.9 or 2.6.26-rc9.

If there is any more info that you could provide, please do so.
(not that I know what it would be)

Hello Randy,

you are right, I can't reproduce it either. I tried several
kernel versions and even downgraded to 2.6.24, checking
whether the configuration settings was lost when switching
from 24 to 25. But this is not the case.

Seems I've lost that particular settings some other way.

I'm terribly sorry for wasting your time. I owe you a beer!

kind regards,
