The disk I plan on leaving attached. I'll look into options for mount; is option "nofail" supposed to mean that it will give up trying to mount if it is non-available? systemd-analyze blame the top four are nmbd.service 10.8s and hciuart.service 6.4s then raspi-config.service 1.3s and smbd.service 1s one is the net bios name server i was pretty sure I dont use that so i disabled it with sudo systemctl stop nmbd sudo systemctl disable nmbd I do use bluetooth, It seems like it is unusually slow. Reading dmesg: uart-pl011 3f201000.serial: no DMA platform data brcmfmac: power management disabled and brcmfmac: brcmf_c_preinit_dcmds; look like firmware warnings raspi-config is probably nominal, though I don't know what it is calling or doing at startup. I use samba smbd.service.
