Teste kernel for a certain capability

Teste kernel for a certain capability

[Mário Gamito]

Hi,

Is there a command one can issue to check if the kernel supports a
certain feature ?

Let's say, for instance, Appletalk, or NTFS.
Whatever...

Warm Regards,
Mário Gamito

something like "make tests"? ;)

not really, one has to actually try to use the feature in question to
determine if the kernel supports it correctly.

And it further depends on the type of kernel, a monolithic one or the
ordinary module kernel. If the latter is the case you could check if
the feature's module is loaded, but ... that's by no means a
guarantee for that the feature will work. May also depend on the
distro you are using, among other stuff.

Rule of thumb: You have to stress-test it

Anything specific you are looking for?

Checking for AppleTalk monolithic support would be nice :)

Hm. Haven't played with that one yet, but what about some script you
run at some time (end) of the boot process? As far as I know,
AppleTalk's purpose was to allow multiple users to share resources.
Check for those; if it works, go ahead, do your stuff, if not well,
time for plan B. I use that kind of approach (feature is present, but
its usability is the point) on my laptop when I connect to my LAN to
check for the presence of backup servers (-> NFS)

As it should be; users better have a backup ;)

If it is 2.6 and it has .config.gz support then you can just extract
the config from /proc, load it in a new kernel and run make menuconfig
to check out whats included.
