Re: Something wrong with mounting, must chroot to run programs

[Capri Corny <capricornyx@gmail.com>]

Now I have compiled and installed the 2.6.39.2 kernel - works well, it seems.
But it did not get the cloop booting any further.
Then I compiled busybox 1.18.5 and placed the new version in minirt.gz.  I tried to pick reasonable compilation flags, but with this version, I can't even  mount mnt-system.  The individual programs in busybox seem to work when tested after unwrapping minirt, so I don't think the trouble is with minirt per se.  With the current busybox at 1.9MB (lots of new system commands are implemented), one might even wonder if, for the specific purpose of cloop and persistent store mounting, just static versions of the system commands might be better?  (Like ntfs-3g is handled now.)

Maybe the best thing is to try a kernel compile, plus eventually, recompile busybox?
Wouldn't this be typical of 32/64-bits linking/loading conflicts?  (I don't know any details here, just know that ELF32/64 libraries can't always be mixed and matched.

Here's my 64-bits type info of the first file busybox isn't able to run:

root@Microknoppix:/store/local/knx_devel# file /bin/mount
/bin/mount: setuid ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

On original Knoppix6.4.4, even if it runs with arch=x86_64, /bin/mount has: setuid ELF 32-bit LSB executable.
Could the dynamic linking have any impact here?
