Is it a problem that SysrescCD is now based on Arch Linux?

Question

From Version 6, released Feb 2 2019, SysrescCD is based on Arch Linux.  This doesn't necessarily mean we can't still use it as a liveCD or rescue cd in most cases, except I found a corner case where it doesn't work.  I happen to run several systems with encrypted LVM as described here.  I had the root volume on one system that needed an fsck journal repair.  I tried to decrpyt it with the lastest sysresccd and found that the cryptsetup/lvm in the sysresccd 6.0.2 could not see my unencrypted volumes.  I rebooted with the last gentoo based sysresccd, 5.3.2 from Nov 2018 and it worked no problem.  It may be that the arch linux kernel doesn't include as many cipher options the older gentoo based kernel as my partition is encrypted with the twofish-xts-plain64 cipher.

There are some other changes that may make sysresccd less desirable as the default install livecd.  

  • no longer fits on an actual CD making the name sort of anachronistic.  I realize most people, myself included, put it on a 1-2GB usb stick instead, but it seems to needlessly foreclose on some older systems.
  • no more 32 bit support.  May not be a problem if funtoo is also dropping 32 bit support.
  • now inits with systemd instead of openrc, not sure if that would matter once chrooted during install, but maybe.  

As time goes on the last gentoo based sysresccd is going to be pretty dated.  Is there a way to engineer metro to build livecds or something?

I don't know if it solves all your points but you can always try out the images at http://192.99.210.63/

Those images are based on funtoo. The description can be found at https://area31.net.br/wiki/LiveCD_oficial It is in portugese but you probably can understand the important parts. And if you have questions about it, you can always ask here or IRC.

Use the Area31 Funtoo livecd -> https://area31.net.br/wiki/LiveCD_oficial

 

is funtoo 1.3 based, we don't need gentoo based livecd anymore.

thanks for the tips.  The last 5.x sysresc image is not too stale yet, but It is good to find a replacement now.  I also found pentoo because I needed to steal a couple ebuilds from their overlay.  Although it is a catalyst/gentoo based system I saw a symlink in the profiles list that was designed to point to either a *.gentoo or *.funtoo file, didn't investigate further.
