have you looked at the LD_BIND_NOW setting for ld.so(8)? from the
fine man page:
LD_BIND_NOW
If present, causes the dynamic linker to resolve all symbols at
program startup instead of when they are first referenced.
do you think this would be helpful? for mount, it would let you even
unmount the filesystem that had the mount program on it from what i
can figure. if you needed this for init specifically (is it all of
init, or just mount?), you could set it up so that there's a knoppix-init
package containing a single script /sbin/init.knoppix which does
effectively
LD_BIND_NOW="yes" /sbin/init
(i'm not sure, you might actually have to make it an exec call to replace
the process)
which should solve your static needs for init, correct? i don't believe
it will take up a considerable amount more of memory either, comparing
it to a static init (there's probably some lib overhead).
alternatively (and i'm a little less certain whether this can be done),
is there any way to pivot back to the initrd as the root filesystem?
that'd make things real simple, right?
anyway, lemme know what you think
sean
