Usually and with maildir there is not much synchronization: postfix drops the mail into the filesystem, and mutt sooner or later finds out that there is new mail. Everything else is just Unix (or the more modern variations of it), these days I would suppose mutt is using dnotify to find out that the directory has changed instead of just polling. In case of mbox file locking is used so that not two programs write to the mbox file at the same time or read it while it is written - file locking is a bit of black magic under Unix (flock/lockf/dotlock - and the interworkings in case of remote filesystems). If you need to know more an can not just move to Maildir ask me, I might elaborate. cu AW -- [...] If you don't want to be restricted, don't agree to it. If you are coerced, comply as much as you must to protect yourself, just don't support it. Noone can free you but yourself.

I'd have been extremely surprised if any connection management utility had an integral recursive nameserver. The latter are complicated projects, which is why there have been relatively few successful ones. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
[DNG] Which beowulf iso to get a manual partitioner
As per subject, I'm looking for hint on which beowulf iso to boot off to e able to manually fix a paritin take an install grub. I have recently run both the beowulf 3.0 and 3.1 desktop iso to carry out installations of a new system. Both of these isos do not provide a manual partitioner and the 'auto partitioner' randomly fails to mark any disk as a boot disk. You end up with a dummy grub install, which is an error and there no way, that I can find to break out and do this manually. Nor could I do it under the expert(?) installation after rebooting to the install. The partitioner just wants to partition it all, when all I want to do is mark one disk as the master boot record and no be forced to do a complete re-install. My 2c is this auto-partition creates a real dogs breakfast of partitions. The auto-created partition table that was created prior(ascii) had free space ESP ext4 swap free space. This time it was just free space ext4 swap (1gb*) freespace I do not know if this weird partitioning scheme was part of the reason for the update grub screwing up. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Yes, basically what I've tried, but there s no /efi/devuan. I've just had no success being able to access any of the file system. i'm begiing to think that if this sort of problems keep recurring, it will be a step back to the future from the time when the first hing you did after installing a system was to created a boot floppy; boot cd/dvd these days. Any way, Thank you. I've decided to risk it and attempt an OS re-install despite the rebuilt mailer requiring three attempts to get a booting sstem. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
