This happens either before init is started, or are triggered by udev, and by their nature will be run in parallel. This will take effect irrespective of the CONCURRENCY option Yes, of course. This was just an example of the non-deterministic mess that we have already. My point is that I'd prefer its getting worse to be optional. -- 73, Ged. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Bug#692559: general: Information missing from man page for rcS
Package: initscripts Severity: normal The man page for rcS is dated 16 January 2006. The parallel boot system added at least one option which is not mentioned in the rcS man page, 'CONCURRENCY'. This option is mentioned in for example http://www.debian.org/releases/stable/amd64/release-notes/ch-whats-new.en.html but it takes a bit of finding (and, given the values found for the existing defaults, the value suggested there is implausible). -- System Information: Debian Release: 6.0.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

This is intentionally undocumented. In previous stable releases, concurrent boot was optional, and if you wanted to try out parallel boot, you had to enable it using CONCURRENCY. Nowadays, parallel startup using startpar is the default. Disabling this is not something which is useful, and so it's not documented as a tweakable option. The option could well be removed entirely in future releases. Regards, Roger -- .''`.

Regarding the above, it would be useful to have some concrete examples to explain why this is the case. The particular case which faces me at the moment may be faulty hardware, incorrect interrupt routing, conflicting interrupts or possibly none of the above.
