I think what I read is that it is done automatically. They could have meant a cron job. I don't think they said how, just that it is already set up to do it. Firmware was mentioned in the thread somewhere so I thought maybe that was it. Either way, fstrim is installed here. It's part of util-linux and that is pulled in by several packages. I doubt it will be going away here anytime soon given the long list of packages that need it. Just to set up a cron job for it. Remembering the steps for that will take time tho. o_O > BTW - Windows does this in Disk Defragmenter but you have to > schedule it yourself according to Bard and ChatGPT.

I currently do the compiling in a chroot on a separate drive. I then copy the compiled packages and use the -k option to update the live OS. I'll continue to do that when I start booting from the SSD. That should limit writes and such to the SSD. I also got to rearrange things so I can put swap on that spare drive I compile on. I don't want swap on a SSD. I wish this thing would stop using swap completely. I have swappiness set to 1 already and it still uses swap. Right now, I'm debating the size of /boot. Knoppix is pretty large. The Gentoo LiveGUI thingy is too. So, it will have to be larger than the few hundred megabytes my current one is. I'm thinking 10GBs or so. Maybe 12GBs to make sure I'm good to go for the foreseeable future. They may limit them to DVD size right now but one day they could pass that limit by. Software isn't getting smaller. Besides, USB is the thing now. Lots of options. Dale :-) :-)
