Re: [gentoo-user] How to determine if a partition is formated
On Friday 10 February 2006 20:05, Iain Buchanan wrote: are you sure? At least for fdisk, (and maybe for 'file' as well) this will just show what you've told the partition it is. 'file' determines filetypes primarily by looking for 'magic numbers' within the file, so 'file' should indeed identify the proper type of filesystem. In fact, if you have a filesystem in a regular file (such as a disk image), it will still properly identify the filesystem. -- # # electronerd, the electronerdian from electronerdia # pgp9gQYFGR67f.pgp Description: PGP signature

If a program uses an instruction that the processor doesn't support, the program will be sent SIGILL, the default action of which is to terminate immediately. Are you absolutely positive of that? I *thought* (would have thought) compilers these days would compile in conditional use of such instructions? That way if large blocks could benefit from these new instructions, they would use them, otherwise fall back to a common set of instructions. Of course this wouldn't be very beneficial for small sections of code. I've been wondering about this for quite some time though, but never bothered to investigate. I'm not _absolutely_ positive, but to do so would likely result in _slower_ code, maybe breaking even occasionally. Using C/C++ as the language: - blocks of multiply-compiled code can be no larger than a single fuction, as the compiler does not know what other functions call that function, and given current build systems, _cannot_ know. Exceptions: inline functions count where the function is inlined, and file-scope (static) functions can be optimized together, but only if they are only called by other file-scope functions, as the compiler can generate a complete list of callers. - the code must be recalculated and duplicated not just for each technology, but for each meaningful and distinct combination of technologies, meaning more conditionals and more branches (and larger code) - code size plays a large role in program performance. Many people report that gcc -Os often gives faster executables than gcc -O3 - How far back do you want to go? Each generation (and brand) of processors adds new technologies and techniques, and the fastest code for one processor may be the slowest for another. -- # # electronerd, the electronerdian from electronerdia # pgpIiINz58oPn.pgp Description: PGP signature

suspect they are just starting then stopping immediately.
I do have psuedo terminals in my kernel, and in fact the config is exactly
as it was with the old kernel.
Any ideas how to troubleshoot this? If you want to see my config file or

Thanks,

hmm... try switching to another virtual console (e.g. ctrl+alt+F1),
logging in as your user and running

Re: [gentoo-user] keeping hosts file in sync
On Wednesday 28 September 2005 07:46, Dave Nebinger wrote: Whats the best way to keep several /etc/host files in sync ? The easiest way is not to bother. Use a local dns server to provide host lookups. I believe on the gentoo wiki you'll find a setup for a caching dns proxy where the most lookups will be forwarded to a regular dns but you can still provide local host lookups and reverse lookups. Works great for me and I don't have to worry about whatever /etc/hosts contains. Also ensures that new windows clients added to the network don't need their files updated, either. In fact, the default BIND install will do the forwarding. I don't know if it's caching, but it definately works well on my (small) home network. I use Webmin for management, and it works great. I also use ISC dhcpd to assign my systems their static internal IP addresses by their MAC address, and to give the location of the DNS server, so I don't have to do any network configuration on my clients. It really works well for me. pgpFUpLAxDUKs.pgp Description: PGP signature

Re: [gentoo-user] ntsysv equivalent (and logrotate frequency)
On Saturday 17 September 2005 20:11, C. Beamer wrote: Hi all, When I installed Gentoo, I chose syslog-ng as my system logger. It was suggested that I install logrotate to prevent my logfiles from becoming unmanagageably large. On my desktop system, my /var/log/messages starts October 19, 2004 and is only 30MB, and I shut down the machine every night. 'tail /var/log/messages' is still just about instantaneous I did this. However, my /var/log/messages file includes logging from the first day that Gentoo was running on my system and that's now about 2 weeks. Is there a default length of time before logrotate will rotate the log files? check in /etc/logrotate.conf. I believe the default is weekly. Also, if your system is not run continuously, you may want to look into anacron, as logrotate is run as a daily cron job For future reference, it is generally best to send separate messages to the list for separate topics. i.e. one message for logrotate, and one message for the service viewer. Makes it easier for potential responders to find interesting questions, and for people searching for answers to find them. Also, does Gentoo have an equivalent to ntsysv where you can set services to stop and start? I assume that when you issue the command rc-update add program name default that this essentially is telling some service to start at boot time. Correct.
