"./strace -f time ls" also produces quite an unexpected output on that system. > IOW: the "detach before exit" might be a necessity even > on latest 2.4 kernels. Need to test 2.4.37... I've made an installation from Owl-2.0-release-i386.iso.gz and updated it to 2.0-stable with linux-2.4.37.9-ow1 kernel, the qemu image could be found at ftp://ftp.altlinux.org/pub/people/ldv/owl/owl-2.0-stable-hd.img.xz Looks like no essential differences from 2.4.32, though. -- ldv
