Try if [ ! -z $modules ]; then

Or if all else fails, read the man page of bash.

I should work at these a bit more before I start flooding lists with
e-mail.  I found a solution that works with loadable and non-loadable
kernels.  Here it is:

16      If [ -z modules ]; then
17        depmod -a
18      fi

I'll keep this one short for a change.

Well, this isn't a complete fix.  I didn't test with modues using the 1.2.1
kernel after my change.  I just ran that test, and despite (I think) it
works, it outputs this now:

Calculating dependencies... /etc/init.d/modules: [: too many arguments
done.

And then loads the individual modules with /sbin/insmod lines.

So this modification would work if [$modules] would work, but modules is a
list, not a text string, so it complains.  So how can I evaluate to 0 if
there are 0 elements, but one otherwise?

Almost had it...

Cheers,

Subject: Kernel Module Errors on Upgrade

Package: base
Version: 93R5

Can't open dependancies file /lib/modules/1.2.10/modules.dep: (No such file
or directory)

This is the bug part
--------------------
This error appeared when I upgraded by kernel.  I suggest that the file
'/etc/init.d/modules' have an if statement added to skip over the error
message if no modules are detected instead of giving the error that it
does.  Actually, the only error is the 'depmod -a' line I think, so I
changed it to

16      If [ $modules ]; then
17        depmod -a
18      fi

instead of just:

16      depmod -a

The rest is echo stuff, so I think this fixes the error completely under
all circumstances.

This is the suggestion part
---------------------------
As I do not have the modules package (which I think I need to make the
modules, don't I?) I am not able to install a modulized kernel.  It again
depends on who your intended audience is whether the default installed
kernel has everything compiled in or whether it uses modules.

I would submit that Linux distributions these days are going to get into
the hands of people which have no clue (even less of a clue than I do) how
to compile a kernel.  These added messages might likely cause a greater
volume of bugs to be reported.  And because I only have the base disks
installed, it took me awhile to use 'ed' to commented out lines in
/etc/modules and /etc/init!  My O'Reilly Nutshell lists ex, it doesn't even
cover ed directly.  I haven't figured out what the difference is actually
(aside from no prompt in ed), but it's an indicator of a possible future
bug for me.  I haven't reported that one, yet...

I am using Debian 0.93R5 alpha, (newly installed) kernel version 1.2.10 and
libc 4.6.27.  I have installed ONLY the base system (and now the new
kernel) for testing purposes.
