--H8ygTp4AXg6deix2 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Under FreeBSD 6.1-RELEASE-p11 with linux_dist-gentoo-stage3-2006.0_2, I find that, on my laptop at least, files installed by portage have incorrect permissions. It seems that the problem can be reduced to utimes(). The following program also unexpectedly changes file permissions but not m/atimes: #include <sys/time.h> int main(int argc, char** argv) { struct timeval timep[2]; timep[0].tv_sec = timep[1].tv_sec = 3600; timep[0].tv_usec = timep[1].tv_usec = 0; if (argc > 1) utimes(argv[1], timep); return 0; } e.g. # chroot /usr/local/gentoo-stage3 /bin/bash # cc -o utimestest utimestest.c # touch blah # chmod 644; ls -l blah -rw-r--r-- 1 root root 0 Dec 20 00:55 blah # ./utimestest blah; ls -l blah -r--rwS--- 1 root root 0 Dec 20 00:55 blah This happens regardless of whether the executable is run inside or outside a chroot. The executable works as expected if compiled under FreeBSD. Before investigating further, possibly trying the utimes linuxulator patch posted earlier, I wonder whether anybody else has had a similar problem?
