Also, Alexander, are all the mounts that are done in the init still
necessary? I tried to mimic what you had in the shell init, but I recall
that a couple of them were workarounds to various bugs.
mount("/.union/dev/shm/.tmp", "/.union/tmp", NULL, MS_BIND, NULL);
still needed in order for glibc pass1 testsuite to pass.
Another workaround (for modules) is no longer there.
I'm asking because on a recent CD I've tested, even though the file
permissions are correct (I double and triple checked that), when you
create an unprivleged 'lfs' user as per the case in the LFS book or the
LiveCD scripts, su as that user, and try to compile a program, the
compile will fail because the user gets 'Permission denied' errors when
trying to read items in /usr/include/linux/
I am going to move from unionfs with bad bug history to known working
cloop + devmapper. This requires either going back to shell scripts (for
glibc-based bash) or learning (not well-documented) libdevmapper.so
functions linking /init against this library. As for insmod, it is not a
problem (in C) either.
But I repeat: I don't think C is a proper language for scripting.
