Didn't someone say something about keeping a "log book" that covered things like how you set up systems in the past?
very difficult and time consuming job. I teached that more than 10 years ago and have some notes, but nor acurate nor complete now

I should update it (and build the server - I already lend one machine) but family get first and is very demanding nowaday :-(

It doesn't have to be time consuming. Even keeping a single text file of subject headings and bullet points is a big win over keeping no notes at all. Any time I solve a tricky or infrequently encountered problem I try to add a note as a reminder for next time. Examples of some of my notes: - ext4lazyinit is slow: - "In order to 'force' ext4lazyinit to finish the thing it does with maximum priority, you need to mount the filesystem with 'init_itable=0'. By default it is 10. ..." - The lazy itable init code will wait n times the number of milliseconds it took to zero out the previous block group's inode table. - can use remount to remount with -o init_itable=0 - samba - Disable the winbind service as it is not used and it delays start of the display-manager.service (sddm login) by making it dependent on starting nmb/winbind. systemctl mask winbind - Change systemd 90s (1:30 min Stop Job) wait on logout/shutdown: Edit /etc/systemd/system.conf Uncomment/set DefaultTimeoutStopSec=20s systemctl daemon-reexec # to get systemd to reload its config - Wayland force KDE Plasma Panel onto a specific monitor Screens (monitors) are defined in $HOME/.config/plasmashellrc searched for panel, and changed lastScreen in $HOME/.config/plasma-org.kde.plasma.desktop-appletsrc changed lastScreen from 0 to 1 I never delete notes just mark them as OBSOLETE. Copy the notes to a device that can be accessed when the machine is offline. Or periodically print them. Michael
