Ok.

I have figured out that when statically compiling busybox ( to glibc ) the
command substitution DOES NOT work.

With dynamic linking, the command substitution works ( i am using busybox in
an initramfs for a bootsplash ).

When doing strace (dynamic linking), it seems libcrypt is used, which I did
not use in my static compile link switches. So maybe that is the problem.

Any ideas?

Hello,

I am using busybox v1.9.0, and I am trying to parse the /proc/cmdline, but
the command substitutions/variable assignments do not seem to work

     cat /proc/cmdline | grep nfsroot

within a shell script (using ash), the above works, but when i do the
following


     NFSROOT=`cat /proc/cmdline | grep nfsroot`
     echo $NFSROOT

it does NOT work, i.e. nothing is assigned to NFSROOT.

Everything works on the host machine (bash). Thanks.
