Jiri? You may remove the files
/lib/mkinitrd/scripts/boot-blogd.sh /lib/mkinitrd/scripts/boot-killblogd.sh /lib/mkinitrd/scripts/boot-killblogd2.sh
and change within

Yes, this stops blogd to flood the console.

But your log shows me that only the two file descriptors 1 and 7 will be used. And as the buffer will be filled with new informations the for-loop on the list of consoles is not an endless loop. That together with the chaning content of the transer buffer (beside the first line) had lead me to the assumption that something goes wrong during compile time (gcc). Maybe this is a problem with my used buffer static unsigned char trans[TRANS_BUFFER_SIZE]; and the cast used below const ssize_t cnt = safein(fdread, (char*)trans, sizeof(trans), noerr); [...] parselog(trans, cnt); for (c = cons; c; c = c->next) { if (c->fd < 0) continue; safeout(c->fd, (char*)trans, cnt, c->max_canon); (void)tcdrain(c->fd); } flushlog(); [...] this is the reason why I've put Michael into the carbon copy list. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The only visible change at tty kernel API is CONFIG_UNIX98_PTYS=y CONFIG_DEVPTS_MULTIPLE_INSTANCES=y <<<<<<< CONFIG_LEGACY_PTYS=y CONFIG_LEGACY_PTY_COUNT=0 that is what does devpts multiple instances do? I do not understand why blogd is able to reread its own messages send to both /dev/tty0 and /dev/ttyS0 even if the console is explicit set to /dev/pts/0 and blogd only reads from the corresponding /dev/ptm0. Does this mean that with the actual kernel blogd has to close all file descriptors for /dev/console (0, 1, and 2) to reopen them after the ioctl TIOCCONS?? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
