Ash execution and VTs

Hi, I'm commiting these to the CVS repository. Previous code had the strange effect of starting the console at the second VT and not executing the shell. The first problem was caused because ELKS wants tty1 to be minor 0 and not minor 1 like Linux, and the other because the Minix file loader was not able to load files with total size (minus 32 byte header) larger than a 16-bit integer -- I wonder how it worked in older versions.

Very good work! But I can't build any image of elkscmd, because it give this error: "/bin/sh: compress: command not found".. I could not realize where compress command is called from. (Error: " * * Building image: comb * umount ./../elkscmd/comb >/dev/null 2>&1 \|\| true dd if=/dev/zero of=./../elkscmd/comb bs=1024 count=720 2>/dev/null /sbin/mkfs.minix -n14 ./../elkscmd/comb 720 >/dev/null mkdir -p /mnt/elks mount -o loop ./../elkscmd/comb /mnt/elks (cd ./../elkscmd/rootfs_template; \ tar cf - --exclude CVS --exclude .keep ) \| \ (cd /mnt/elks; tar xpf -) for i in sys_utils ash bc byacc disk_utils file_utils levee m4 minix1 minix2 minix3 misc_utils mtools sash sh_utils inet; do make -C $i min_rfs\|\|exit 1; done >/dev/null /bin/sh: compress: command not found make[2]: [install] Error 127 make[1]: * [_populate_target] Error 1 make[1]: Leaving directory `/home/eddy/elks/CVS/elkscmd' make: *** [comb] Error 2 ") P.s.: I attach again my patch for elks makefile etc., now I had the time to try it, and it works.. you can also accept just part of this.. as you want, but at least the correction in arch/i86/drivers/char/KeyMaps/mkcfg that now make menuconfig to crash if you enter in character device menu. About menuconfig I noticed that there is an error: in multi-choice menu, if you press escape, instead of return at the parent menu, it shows help, this is not a big problem because you can just press enter to solve it, but if there is a number choice, it enter in a continuous loop as also the enter key shows help.

Hello, compress is called from the mtools makefile to compress man pages -- you can either install compress on your system or comment out that line in the makefile. > - -t -M -o $(ARCH_DIR)/boot/system > System.tmp ; \ > + -M -o $(ARCH_DIR)/boot/system > System.tmp ; \ Good catch, it seems that we had some unnecessary stuff on System.map. Mike, any probkem if I commit Eddy's patches? I'd leave the debug option out for now, I had some problems building the kernel with full debug when tracing the minix executable loader. - To unsubscribe from this list: send the line "unsubscribe linux-8086" in the body of a message to majordomovger.kernel.org More majordomo info at http://vge r.kernel.org/majordomo-info.html
