[gentoo-user] postfix: /etc/postfix/aliases or /etc/mail/aliases ?
I have an old log warning I want to clean up, and am assuming that the aliases and aliases.db file would typically be in the same directory. When the postfix service starts at boot; postfix/postalias[607]: fatal: open /etc/postfix/aliases.db: Read-only file system The location is currently configured in main.cf; # postconf alias_maps alias_maps = hash:/etc/postfix/aliases And looks like the installer puts the original alias file there too, so I assume my config is per the default config; # qlist postfix | grep aliases /etc/postfix/aliases But this; # grep aliases /lib/systemd/system/postfix.service ExecStartPre=-/usr/bin/newaliases ReadWritePaths=-/etc/mail/aliases.db Suggests that /etc/mail is the correct location, so i'm wondering if i missed an update to postfix.service. Can a postfix user please check their ReadWritePaths to see if it's /etc/mail/aliases.db or /etc/postfix/aliases.db ? Cheers.

Re: [gentoo-user] Inquiry about gentoo kernel configuration
Yes, but the image does not need to be up-to-date, since you only use it temporarily; everything else is done in a chroot environment. One thing to mention, though: The LiveDVD can be booted from UEFI, which you will need to finalise[2] the Gentoo installation on a UEFI system. As William already mentioned, you can boot from almost any Linux live media and install Gentoo[1] from there. -Ramon [1] https://wiki.gentoo.org/wiki/Handbook:AMD64/Full/Installation [2] See important note: https://wiki.gentoo.org/wiki/Handbook:AMD64/Full/Installation#Booting_the_installation_media On 11/07/2021 15:11, Dongliang Mu wrote: On Sun, Jul 11, 2021 at 1:23 AM Ramon Fischer wrote: In addition to this: I did some further research about this, since I actually never thought about getting the Kernel sources without having an installed Gentoo system: You may take a look at one of the HTTP mirrors[1], preferably one in your country and navigate to "/releases//".

Or grab another distros boot directory (containing the kernel, initrd and config files), the matching /lib/modules directory and boot that instead of building your own (I do this often on uboot based arm systems and raspberry pi's.)

Hi, look here: https://github.com/mgorny/gentoo-kernel-config In names of gentoo "packages" the -bin suffix indicates that it is a pre-built, binary package, so the maintainers use a configuration, build the kernel and upload everything as a binary package. Portage than installs the binary package when you would call 'emerge --ask gentoo-kernel-bin'. Some hints for reading ebuilds and finding stuff: The ebuilds are basically bash scripts, and to find functions called inside each ebuild you can search in the eclasses dir in https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass while you can find (most) of the eclass names from the line starting with 'inherit'. To find e.g. the link to the config I used the following workflow. Maybe it'll be of usage for you, too: https://packages.gentoo.org -> gentoo-kernel -> Git repository browser -> choose the package version -> link below: https://gitweb.gentoo.org/repo/gentoo.git/tree/sys-kernel/gentoo-kernel/gentoo-kernel-5.12.15.ebuild#n20 Kind regards, Nils

There are a few bin(ary) kernels in portage/sys-kernel/* that > might work for you but I have never tried them. I see, thanks for your explanation. Gentoo people seem to build everything for their systems, including the underlying Linux kernel. For the installation CD, it plays a role as a temporary system to install the real Gentoo Linux. So there should be no default kernel configuration files. It depends on the Gentoo user, right? > > You can boot almost any linux live media on your target hardware and > extract the config (sysrescuecd is a good one) and use their sources, or > build the kernel using their config on top of Gentoo's vanilla-sources, > or gentoo-sources. > > Or grab another distros boot directory (containing the kernel, initrd > and config files), the matching /lib/modules directory and boot that > instead of building your own (I do this often on uboot based arm systems > and raspberry pi's.) > > Or ask on the list if someone has a config that matches your target > (occasionally it comes up). > > BillK > > > > > > [1] https://www.gentoo.org/downloads/ > > > > On 10/07/2021 11:15, Dongliang Mu wrote: > >> Hi Gentoo users, > >> > >> I am a newbie to Gentoo.

Re: [gentoo-user] Problems with LyX and xetex-2021
Hi Stefano,
I couldn't reproduce your error with xelatex at all. I took your example/MWE
and just executed "xelatex test.tex" and it generated me a single page PDF.
A quick and dirty idea: Move ~/.texlive (e.g. to ~/.texlive-bak) and let texlive
regenerate files there.
In my worldfile I have app-text/texlive, dev-tex/biber and dev-tex/latexmk,
everything else are just deps.
Interestingly it works even with USE="-xetex" for texlive which in turn has only
the following USE flags enabled:
"X extra graphics luatex metapost music png pstricks science truetype"
Hope that helps you,
Nils
