You can replace the original root subvolume with the snapshot.

[gentoo-user] How to replay a backup system?
Hi, from time to time - as was the case a few days ago - Gentoo updates lead to an unbootable system. I backup my system each day - using BTRFS snapshots. Now, only a few files on current system have changed; the rest of the 400 GB root partition is unchanged. Therefore I only have to replace these newer files by the versions saved a day before. How can this be done efficiently? Unfortunately AFAIK rsync doesn't have an option to copy only files which are NEWER on the destination than the corresponding files in the backup. Many thanks for a hint, Helmut

Hi,
I have been built (and used successfully) nearly each kernel of the

I've copie the old config to the new kernel directory and did "make

Suddenly with Kernel 5.16.{3,4,5} these kernels hang during boot.

Hi, Is there anything faster than rm -rf ? I'm using rync with the --link-dest= option. Since this option uses hard links extensively, both, and have to be on the same file system. Therefore, just re-making the file system anew, cannot be used. There are more than 55,000 files on some which is located on a BTRFS file system. Standard 'rm -rf' is really slow.

Therefore I'd like to create a (big) file - say EXT.raw - there and mount it as a loop device. Under root (tsu in Termux) this is not a problem, but I cannot access this new device as non-root user in Termux.

Hi Helmut
I believe this is a consequence of the sandboxing of ebuilds.
When I had the same problem with an ebuild trying to download many
things from
the Maven repository, I added the following lines inside the ebuild:

_h_t_t_p_s_:_/_/_r_e_p_o_._m_a_v_e_n_._a_p_a_c_h_e_._o_r_g_/_m_a_v_e_n_2
RESTRICT="network-sandbox"
It is described (shortly) in "man 5 ebuild"
This is forbidden in the Portage tree, but is allowed in your own
overlay.

[gentoo-user] Gentoo's Python policy drives me crazy
Today's updating involves some package which causes rebuilding a package which needs Python2.7 and another one which needs python_single_target_python3_8 required by that mysterious @__auto_slot_operator_replace_installed__ To emerge the Python2.7 package (Scribus) I do need to set PYTHON_SINGLE_TARGET="python2_7" in /etc/portage/make.conf which makes the whole update fail since the other packages needs PYTHON_SINGLE_TARGET="python3_8" So, what can I brave Gentoo user do? Hopefully something better than trying to find which new package triggers which rebuild.
[gentoo-user] PYTHON_TARGETS something must have changed
Up to a few days ago I had PYTHON_TARGETS="python3_8" in /etc/portage/make.conf and for any package to be installed for Python2.7, I had something like media-gfx/cropgui python_targets_python2_7 in /etc/portage/package.use But now, I have to add python2_7 to PYTHON_TARGETS whenever I want to emerge a package which needs Python2.7 But keeping PYTHON_TARGETS="python3_8 python2_7' in my make.conf will install an (additional) Python2.7 version whenever the package has python2_7 in PYTHON_COMPAT in its ebuild file. Furthermore I would have to add more and more -python_targets_python2_7 in /etc/portage/package.use for any package which does not support Python2.7, any more. I am on the 17.1 desktop profile and use the GIT version of portage. What has changed and what can I do about it? Many thanks for a hint, Helmut

any idea what's the easiest way to get 2.80 or 2.81 running on gentoo?
and any idea how when to expect the 2.80 or 2.81?
You could copy the attached ebuild to a local overlay like
/usr/local/portage/media-gfx/blender
and copy the attached patch to
/usr/local/portage/media-gfx/blender/files
run
ebuild /usr/local/portage/media-gfx/blender/blender-.ebuild manifest
and then
emerge -av1 media-gfx/blender
This gives you the most recent version of blender.

On 06/18/2019 05:43:55 PM, John Covici wrote: It would seem impossible for me to switch to profile 17.1. I say this because I can never run emerge --depclean .

Inn no longer configures and I have discussed this in another thread. So, where can I go with this? I hate to just go forward, although these packages look they don't have any lib32 dependencies. Wat do you thihnk about this? Thanks in advance for any suggestions. I haven't run emerge --depclean. I have re-emerge gcc / glibc and all packages with files /usr/lib32 and /lib32 and some more which I don't remember. On the other hand I don't see such a big advantage of profile 17.1. I have several (64 bit) packages (in my local portage tree) which still install into /usr/lib although this folder is now the replacement of the old /usr/lib32. But I don't know if we sometimes forced to switch to a successor of 17.1. Helmut
[gentoo-user] Heads Up - switching to profile 17.1 is not as easy as it sounds
I had some trouble switching to the new profile 17.1. Following the advice in the news item didn't suffice. I had to reinstall some packages "by hand", e.g. I had to reinstall util-linux quite early. I had to reinstall x11-libs/libva without the opengl USE flag, since it couldn't find libopenGL otherwise. After reinstalling mesa (which depends on libva), I'll try to reinstall x11-libs/libva with the opengl USE flag. Currently I'm reemerging gcc bintuils glibc before I proceed with the other packages selected by emerge -v1 /usr/lib/gcc /lib32 /usr/lib32 Perhaps, it's only me. Helmut

Re: [gentoo-user] CUPS remote printing drives me crazy
Many thanks to all who helped me. For cupsd.conf on the server machine It turned out that I needed Listen localhost:631 in addition to Port 631 Listen /run/cups/cups.sock Furthermore, on the client machine I had typo DeviceURI ipp:://MyServer/printers/duploc_usb (note the double colon) Unfortunately, CUPS doesn't seem to check the syntax of DeviceURI or it doesn't report this. One simply gets "printer could not be located" when one tries to use it. I didn't want to use enter the SERVER name into /etc/cups/client.conf on the client machine, since I want "double spooling', i.e. the client machine should accept the print job even if the SERVER machine is down. --- Yes, I still have an old printer which only has a USB-connection and an Ethernet connection. Unfortunately, the Ethernet connection broke down recently. I don't think that WiFi is the best solution since - at least me - have only 60 Mbits/seccon on the WiFi but 1 Gbits/second on the wired Ethernet - and some files to be printed are quite large.

[gentoo-user] eselect mystery - please help
Hi, after an emerge --dep-clean yesterday, I've noticed today that I don't have any java-jkd / jre available anymore. Although I've emerged dev-java/oracle-jre-bin dev-java/oracle-jre-bin eselect java-vm list doesn't show these. How make these "visible" to eselect again? Many thanks for a hint, Helmut

You should file a bug about it. Is there a special requirement for building ncurses with tinfo? If not the easy fix is disabling the tinfo USE flag for ncurses. Many thanks, Daniel. I can't remember why I HAD TO add the tinfo USE flag to ncurses.
[gentoo-user] ncurses / tinfo problem
Hi, there are several packages which fail to link since they are missing '-ltinfo' - recently app-antivirus/clamav-0.99.4-r1 For a temporary fix I have edited the config.status file by changing S["CURSES_LIBS"]="-lncurses" to S["CURSES_LIBS"]="-lncurses -ltinfo" and using ebuild /usr/portage/app-antivirus/clamav/clamav-0.99.4-r1.ebuild merge But I think that this is a more general problem.

[gentoo-user] QEMU on a partition
Hi, I'd like to install a second Gentoo system on a partition by running QEMU using that partition (directly) - this is to create and update a Gentoo system with different CFLAGS (for an older machine). Having no experience in such setups my initial problem is how to install grub2 on that partition (only). I don't want to modify the MBR of the whole drive containing that partition. Is is possible?

High Marc, I think I need the opposite : only update files which are newer on the receiver Thanks, Helmut

[gentoo-user] Heads Up - glibc-2.27 breaks my system
With glibc-2.27 installed I cannot compile anything, since most packages try to include which doesn't exit any more. And downgrading glibc using a binary package doesn't work. It looks like I have to restore my system from a recent backup, very annoying! (I know that glibc-2.27 is masked, but I didn't expect it to be bomb like that) Helmut

If I read the =app-text/pdftk-2.02 ebuild correctly, it actually
uses
GCC 5.4.0, regardless of what your system compiler is (6.4.0
for
profile 17.0):
# We need gcc-5 because of Java
export PATH="$(gcc-config -B 5.4.0):${PATH}"
Yes, but you can change this to
RDEPEND="sys-devel/gcc:6.4.0[gcj]"
which works just fine.
