Thanks, Darac. Now I know it's systemd, not apt. On the desktop, 'systemctl list-devices' says, among other things: ● -.mount masked active mounted Root Mount ● amandaDisk.mount masked active mounted /amandaDisk ● blackHole.mount masked active mounted /blackHole ● boot.mount masked active mounted /boot dev-hugepages.mount loaded active mounted Huge Pages File System dev-mqueue.mount loaded active mounted POSIX Message Queue File proc-sys-fs-binfmt_misc.mount loaded active mounted Arbitrary Executable File ● raid1Array.mount masked active mounted /raid1Array Why is systemd trying to mount /? /'s already mounted or systemd couldn't run, not so? And doesn't that say / is mounted and active? And completely disabled (masked)? Isn't active/masked a contradiction? All of those with the dots are in fstab. / on the desktop is an nvme, if that makes any difference. On the laptop it's a vanilla SATA. Desktop /boot is a thumb-drive because the elderly BIOS will boot USB and the Debian startup software knows how to read an nvme. Sorry to not understand systemd and its buds very well at all. -- Glenn English -----BEGIN PGP SIGNATURE----- Version: ProtonMail wsBzBAEBCAAGBQJgqV5zACEJEJ/XhjGCrIwyFiEELKJzD0JScCVjQA2Xn9eG MYKsjDJpyQf+J4q+UFK+//WiEi59f1YUFbndUz5ayjfMsj1uURj7/R59zxEw qySvh/Lg51pUkAgTh7IvnCwtE2WUD37XcET1N8B3a1B1ldSw/qS+TVptu4MF i2SFqt75K111z/nvBU/BqflkYAJATPJIK4pETHG1091rN+pb47mxJWLt4hCI xvy6Bkjm6ppHqUj7toJKQ+jZPp1KPXDn+6VC5Nd+Uq1RUcrJ+dYh5hp8drVw XDC3/Uvt6QXn4bxLgbhM2BHT6koBWvwkOGIfZmfvwZjIbcG1kjplDqtGLYXs kpvJ4KtUF3bHdkojvX198UW3trJjpN8eAjxw3IQJGA3ZJWkW/33tmA== =4Vl1 -----END PGP SIGNATURE-----
