Re: [gentoo-user] SSD configuration
Well, with 8Gb RAM, i recommend use tmpfs on PORTAGE_TMPDIR, just while u are compiling anything. Or even with 6Gb too. I don't worry to much about use the SSD, the only thing that i do is use distfiles, music/video/photos on HDD to safe space. And the TMPDIR thing when i'm compiling a lot of things. 2012/11/26 Jacques Montier jmont...@gmail.com 2012/11/26 Daniel Troeder dan...@admin-box.com On 25.11.2012 22:43, Jacques Montier wrote: Each time you sync the portage, you should write on the SSD...

Re: [gentoo-user] SSD configuration
Nice way to handle that. I only had problems with libreoffice. But i mount the tmpdir ondemand, and when libreoffice needs update i use the SSD instead.

Re: [gentoo-user] SSD configuration
I think u misunderstand, i belive that what Schuster have is tmpfs always mounted on /var/tmp/portage, and PORTAGE_TMPDIR will be that. When he need more than 8Gb in some package PORTAGE_TMPDIR will be /var/portage/tmp and that on HDD. What i have is /var/tmp/portage on tmpfs config in fstab with noauto, so when i want to emerge a lot of things i mount that. 2012/11/26 Jacques Montier jmont...@gmail.com 2012/11/26 Alex Schuster wo...@wonkology.org Luis Gustavo Vilela de Oliveira writes: Well, with 8Gb RAM, i recommend use tmpfs on PORTAGE_TMPDIR, just while u are compiling anything.
