-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I'm used to test the software which I use with dietlibc, just to see if it could run without the bloat of glibc.

I guess what I wanted to say is that it might be desirable to have the klibc shell do some dancing (perhaps controlled by some flags, but on by default?) If getpid() == 1 then fork a child, continue in the child, have the parent wait for the child to terminate, then exit child should setsid() close(2) close(1) close(0) open("/dev/ttyS0", O_RDONLY) open("/dev/ttyS0",

Does ctrl+c work? My experience with (non klibc) init=/bin/bash is that getting ctrl+c to work requires some jumping through hoops, because running as pid 1 doesn't really work. If I recall correctly you have to call setsid, and open a tty as a controlling tty, you can't call setsid as pid 1. The hack that I got to work (for reference, I'm using this for raw kernel testing

Allow an alternate libc, such as dietlibc, to be used for the init binary in the supermin appliance. Rich.

Don't know why it works, but it works ... Rich.

Removing this ioctl call fixes this. I noticed the problem because supermin's init compiled with dietlibc worked, since the dietlibc header files don't define TIOCSCTTY and hence the ioctl was not called. --- init/init.c | 4 ---- 1 file changed, 4 deletions(-) diff --git a/init/init.c b/init/init.c index e6fd0e6..aa6c25f 100644 --- a/init/init.c +++ b/init/init.c @@ -240,10 +240,6 @@ main ()...

v1 -> v2: - If we split out the init program into a separate init/ directory, that makes it much easier to build against an alternate libc. I tried to build against uClibc, but uClibc requires an entire build chain, which looked like it was going to be a massive ballache. Rich.

Cc the Linux/m68k arch list for the m68k patch, to review.
