Re: [gentoo-user] What does emerge status R mean?
The R status means REBUILD. Usually, if it's an @world it's pulling that in because something about that package changed and so it needs to rebuild it. The --noreplace option would block that if portage didn't think it was needed. Based on your options, I'd say that it's probably a USE flag was changed. I don't use binpkgs myself, preferring to compile except in certain circumstances (can we say RUST!?) that I need to use a -bin variant. You can try without it, but I recommend leaving your change-use and newuse flags in place and letting the system rebuild xmodmap.

Could be a random, erroneous write to disk or something in the kernel compile didn't go well. I'd suggest also rebuilding the initrd and reinstalling grub. I.e. I think there is likely a kernel compile issue since it doesn't ever launch the kernel succesfully either on autopilot or when you run grub interactive. Might also recompile grub, perhaps there's a change in compiler options that produces an incompatible (at least partially). I also suggest the rebuild so you can be sure you have the right initrd and matching kernel.

Good thought - I just now got a successful boot using efibootmgr. Peter Humphries also suggested that somewhere in this thread, but also stated that he couldn’t get grub to work on the same brand mobo (Asus). I’d almost believe that it’s a grub-Asus thing except for the fact that Sysrescue and Ubuntu both boot successfully. And I think they use grub. Maybe time to experiment with a different version or fresh installation of grub. Except that I’m burnt out on booting. Think I’ll go outside and dig some holes. John >

FWIW:
For one: why not filter the iptables messages into a seperate logfile?
E.g. for syslog-ng (you'll need to add the filter to other
filters/log, having them in the filters you can use those
more intuitively):
filter f_iptables { facility(kern) and message("IN=") and message("OUT="); };
filter f_console{ ... and not filter(f_iptables); }
filter f_messages { ... and not filter(f_iptables); };
filter f_warn { ... and not filter(f_iptables); };
[..]
log { source(src); source(chroots); filter(f_messages); destination(messages);
};
# Firewall (iptables) messages in one file:
destination firewall { file("/var/log/firewall" suppress(30)); };
log { source(src); source(chroots); filter(f_iptables); destination(firewall);
};
You might be logging more specifically, so you could add more specific
filters. That's what those filters (and log-prefixes in iptables) are
for after all :)
Also add a matching logrotate entry:
/var/log/firewall {
delaycompress
missingok
notifempty
size +4096k
sharedscripts
postrotate
/etc/init.d/syslog-ng reload > /dev/null 2>&1 || true
endscript
}
or some such as /etc/logrotate.d/firewall (or however you name you
iptables-logfile.
And second, how about setting up a local dnsmasq to send all fb-crap
to NXDOMAIN on the DNS-level?
dnsmasq.conf or e.g. /etc/dnsmasq.d/blocklist.conf [1]
address=/fb.com/
address=/fb.me/
address=/facebook.net/
address=/facebook.de/
address=/facebook.fr/
address=/facebook.co.uk/
address=/facebook.com/
address=/fbcdn.net/
address=/instagram.com/
address=/instagram.de/
address=/whatsapp.de/
address=/whatsapp.com/
address=/whatsapp.net/
That has the effect that all (sub-)domains with those names give
NXDOMAIN, i.e. are non-existant. Compare to:
$ nslookup there.is.no.such.domain.invalid
Depending on what sites you visit, you might add more domains like
e.g. facebook.ca, facebook.mx, facebook.es or whatever fb-domains
sites that you visit include...
Just as ideas,
-dnh
[1] you'll need a matching conf-dir or conf-file directive, preferably
at the end of the main /etc/dnsmasq.conf then, I use:
conf-dir=/etc/dnsmasq.d,*.conf
which includes all *.conf files from /etc/dnsmasq.d/ (and ignores
other files there like *.conf~ or Makefile or whatnot, so you can
be creative and e.g. generate your blocklist from a simple list of
domains ;) E.g.:
/etc/dnsmasq.d/Makefile
all: blocklist.conf
blocklist.conf: blocklist.conf.in
sort -u $< | sed 's@\(.*\)@address=/&/@' > $@
You get the ideas ;) (and if not: ask!)

Tried dracut. No change. Added the kernel command line debug options (#3 in “Identifying your problem area” in ‘man dracut’). No change. Feeling peevish, I made a file of random junk using dd if=/dev/random of=initrd.img count=4096. Then supplied that pile of junk as the initrd. Again, no change.

So, it’s getting as far as wanting to read the initrd, and is smart enough to tell whether the specified initrd actually exists on the specified boot partition.

That suggests to me that grub has failed to load linux and/or the initrd into memory, or that it's failed to hand execution control to linux. Next step: learned how to run an interactive grub2 command shell. With full debugging turned on, it looks like grub2 can load the kernel image, and it looks like it loads the initrd as well. At least there are no complaints and the reported initrd size looks correct.

[gentoo-user] Building kernel without messing the kernel source tree
I am looking to compile the Linux kernel and send the work and output to another directory, thereby leaving the kernel source tree directory clean. If I build gcc or other software using configure script, I can go to another directory and run, for instance, ~/builds/gcc-8.3.0/configure --prefix=/usr ... without dirtying the source directory. This would likely be a cross-compile from NetBSD or FreeBSD. Could I do make -C ~/builds/linux-4.19.105 ARCH=x86_64 CROSS_COMPILE=x86_64-linux-musl- ... ? That would be my first thought, seeking to avoid having to clean after every run, successful or unsuccessful. Avoid the worry about whether clean, distclean or mrproper work. I would like to compile for x86_64 and also i486 (or would that be i386)? Is this a question for gentoo-user or gentoo-dev? The "make" I use is built from GNU source, not /usr/bin/make as is found on NetBSD or FreeBSD. Tom

I have an Asus X99-A motherboard, and I never got grub to work at all. I use a combination of efibootmgr and bootctl to manage my boot process. (Bootctl is in sys- boot/systemd-boot; that's the only systemd package I have on this openrc system.) You could look at the handbook [1] for how to set these up. I had to develop my own method by picking bits out of it. I use efibootmgr to create entries in the UEFI BIOS, then bootctl to keep them up to date. Oh, and I had to leave a small, otherwise unused partition before the FAT32 boot partition. From parted: Number Start EndSize File system Name Flags 1 1.00MiB9.00MiB8.00MiB 2 9.00MiB1025MiB1016MiB fat32 boot, esp 3 1025MiB50176MiB 49151MiB linux-swap(v1)swap 4 50176MiB 66560MiB 16384MiB ext4 5 66560MiB 132096MiB 65536MiB ext4 [...] This may be a red herring of course; I wouldn't be too surprised if I'm doing things all wrong, and your motherboard may differ from mine in many ways. 1. https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Bootloader[1] -- Regards, Peter.

I am not sure genkernel uses that exact name but I did need to find the initramfs boot log to diagnose a failure in a genkernel initramfs at one time. BillK
