Two months later...
After my Chimera trials ended (current status : my Pbook and I aren't up to the task for now), I read about Void and decided it looked like a "
sweet spot" of CPU power requirements vs usability/fun to use, so went on to install it on my Alubook. Of course knowing that the distro has been put offline, got the ISO's from the web archive
here.
First tried Void-musl+XFCE which worked fine from Live session but failed to install : SSD not detected.
Moved to non-musl distro, again Live session Ok, SSD detected but the installer fails toward the end.
Finally tried the base non-musl distro, which installed successfully - however kernel 5 would refuse to boot, so have to use kernel 4.4. Not sure how much of an impact this might have on the overall functioning of the distro on my Alubook 12".
Then went on installing xorg, LightDM and MATE from one of the Europe-based mirror repos, both working fine, though can't get neither the DM nor the DE to remember to default to FR keymap i/o US. In the process learnt a bunch of tips, like using
ntpdate time.cloudflare.com
to get a valid current date/time (main and CMOS batteries both dead), how to launch a service with runit via symbolic links, pretty neat, etc...
Then installed among others Firefox, Filezilla and Evolution (mail/calendar client, trying to avoid the bloated Thunderbird), then Spiderweb, all work fine, I'll probably want to try ArcticFox next see how it performs vs the others but quite happy with Spiderweb for now (kudos and thanxx again go to
@wicknix). Got audio to work with the alsa packages, however right now Wifi and BT both not working, tried to install the b43 drivers but no success yet, WIP. (need to go thru the 36 pages of the Void-PPC thread, at p.4 for now). Oh yeah, and need to switch to EN as the OS language, can't deal with menus in FR ^^.
So overall quite happy with Void-PPC, looks very promising as a "daily driver" on my 2004 Alubook (not necessarily with MATE though, I'll try other DE's to see which one works best), in fact I also installed the latest Void release as a Win11 Virtualbox VM to get familiar with it (and some apps like Evolution), pretty stable so far though it freezes and I have to power it off and restart it like once a day, not too bad I guess. Might in fact become the distro I'll install on my mini-PC as the main OS (and Win11 degraded to a VM or dual-boot status, will still need it at least for a while).
