It's kept updated regularly for security. See
http://www.palemoon.org/releasenotes.shtml for update info. "CVE-"
mentions are usually for code inherited from Firefox. The reason the
version number is "so low" is that update increments tend to be +0.0.1
instead of full integer +1 like Firefox/Chrome. Major milestones are
where the integer increments occur. I believe that performance is
roughly the same, but I don't use both, so I don't definitively know.
BTW, Pale Moon is still XUL, versus Firefox Webextensions, so the
respective addons/extensions are incompatible. Pale Moon stuff is listed
at https://addons.palemoon.org/extensions/
> Would they differ in performance terms on an old AMD powered laptop?
1st question; how old is the AMD laptop? Pale Moon requires at least
SSE2-capable cpus.
2nd question; how old is the AMD laptop? As per thread
https://forum.palemoon.org/viewtopic.php?f=37=23031 the official
32-bit tarball will no longer be generated as of Nov 2020. Note that
this will not prevent you from building it yourself in Gentoo or "the
hard way", or "community versions" or whatever.

You can go the overlay route to manage it by Gentoo, but remember to
disable system libs. This will continue to work for 32 and 64-bit.
Or you can pull down the tarball and extract to your home directory
and point your program launcher to ${HOME}/palemoon/palemoon The entire
program is contained in ${HOME}/palemoon so it doesn't splatter stuff
all over. "Uninstalling" consists of "rm -rf ${HOME}/palemoon". You
can set it to auto-update (64-bit only after November) if you install it
in a directory that you have write-access to.

Cheers, Wol Yes, that's an issue ... there's two swap files. One is on the root dir and that one is the only one that came up active when I started the system this morning. The other one is on a mounted fs. Earlier, I'd had it on the following line to that fs, and as an admittedly feeble attempt, I moved that swapon to the bottom of the file - who knows if those lines are processed sequentially. But it didn't help. But, the thing is, the swap partition is also not mounted by its fstab entry. That wouldn't need an fs to be mounted.

A clock that varies like that is usually referred to has a "spread-spectrum" clock. If properly implimented it has no measurable effect on software execution (even for real-time cases) because the variation is done so that the average frequency is "constant" and the deviation from that average sums to 0 for any significant period of time (anything over a few hundred microseconds). The variation of the average over temperature and supply voltage is usually far more significant. -- Grant Edwards grant.b.edwardsYow! PIZZA!! at gmail.com

As a chroot is not a complete system, you will also have to do some more actions inside the VM - Compile and install a kernel [1], probably with the VMware modules to get better performance. - Tell Grub to include that kernel in the list of boot options [2] - Check that an init system is fully configured, you can choose between OpenRC or SystemD [3] - Configure networking inside the VM [4] and in VMware on the host - Add services like SSH to system start to be able to connect to the VM As you can see, this will be a mix of a fresh install and a migration of your chroot. Basically you can read through the Gentoo Handbook to see what steps are necessary for the VM to boot. When you copy the chroot files into the VM they will overwrite files from the Stage3. I believe the best step to do this is just before the "Installing tools" chapter, but their may be side effects I don't anticipate... The good thing about a VM is that if anything goes wrong, you just trash it and restart ! Tell us how things turn out for you.

There are VMWare applications to convert a physical installation of an OS to a VM disk, but since the guest OS is linux, the way I would do it would be: 1. Create a virtual disk of the desired size. 2. Attach a LiveCD to the VM and boot with it. 3. Use the LiveCD environment to partition/format/mount the VM disk. 4. Use rsync to copy the filesystem contents from the chroot to the VM partitions. 5. Edit the copied fstab to correspond to the VM disk partition UUIDs and potentially reinstall GRUB. 6. Unmount the VM disk partitions, shutdown the VM, detatch the LiveCD and restart the VM. You could use partclone instead of rsync, which would retain the same UUIDs and filesystems as the chrooted system and therefore simplify the migration.

What gives? My reported CPU frequency is also slightly lower than the values reported in 'scaling_available_frequencies' and it fluctuates as the load on the CPU varies. I take these values to be rounded upper limits, rather than what the CPU will be pegged at. MoBo firmware plus kernel options seem to control (limit) the CPU frequency. I was installing Gentoo on a laptop, using a minimal CD and the CPU thermal cut out would kick in every time I tried to install packages shutting down the PC. The frequency at the time reached 3600-3900MHz. After I completed the install by limiting jobs and using an external cooling fan, I booted with my own newly configured kernel. I felt disappointed to notice the frequency would never go above 2500, no matter what scaling_governor I used and what max frequency I selected. I also tried using sys-power/cpupower to manipulate governors and frequencies, but nothing would change this hard limit of 2500MHz. I can't recall what the LiveCD was missing in the kernel/packages - it might have been acpi-freq. This is the current state of affairs: $ cpupower frequency-info analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 4.0 us hardware limits: 1.40 GHz - 2.50 GHz available frequency steps: 2.50 GHz, 2.10 GHz, 1.80 GHz, 1.40 GHz available cpufreq governors: ondemand userspace performance schedutil current policy: frequency should be within 1.40 GHz and 2.50 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.31 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes Anyway, since I couldn't push it above 2500MHz, I've left it alone running on schedutil and it never overheats or cuts out. signature.asc Description: This is a digitally signed message part.

It went well. No problems. Still, when something goes wrong with elogind, I'm trying to figure out how to recognize it. The biggest thing I don't like, it being in the boot runlevel. It requires me to remember to restart it after a upgrade. If I forget, I run into the issues in this thread. From my understanding tho, consolekit is leaving the building. At some point, switching will have to be done. When I was restarting elogind yesterday, I had a process that was taking up one core as well. I went back to the boot runlevel, stopped elogind, killed any straggling processes and then restarted elogind and back to default runlevel. So far, everything is working fine. It could be a fluke, it could repeat and be a bug of some sort. I'll know next time, if I remember to check. lol Dale :-) :-)

[gentoo-user] Migrating chroot to VM
I want to do a crazy thing. I want to migrate my gentoo installation from a chroot to a VM (both on the same host). The host is debian but I can only use SSH. What do you suggest to do?
[gentoo-user] Firefox display oddity
Hello list, This is www-client/firefox-68.5.0. From time to time, when I switch desktops to it, FF doesn't show the tab bar. The odd thing about it is that the mouse pointer picks up displayed objects as though the tab bar were on display, so I have to aim half an inch below what I want to select. Then, pressing shows the tab bar, not the menu bar, which remains hidden, and the mouse picks up the right objects - until I click something, when the tab bar disappears again. I think this is expected behaviour, given the misbehaviour. Recompiling FF seems to be the only way to recover from this. -- Regards, Peter.
