Root file-system not properly umounted on shutdown/reboot
My system is set up with separate file-systems for /boot (ext2), /home(ext4, no journal) and /(ext4, no journal). I do not use a desktop system, just a window manager (xmonad). If I reboot or shut down while X and the window manager are running, the root file-system gets fsck-ed upon rebooting. If I exit from the window manager and X before shutting down or rebooting, then the root file-system is clean on the next reboot.
I am not sure that the correlation I’ve established above between improper umounting and X still running is strong. I will update this report as I get more data. But I can say definitively that there is an issue with shutting down/rebooting Alpine and umounting of the root file-system.
