Hello, I'm running GuixSD.
I tried to 'eject' a pen drive today using `sudo eject /mnt/usb` The command failed with -------8<---------------->8----------- eject: unable to exec /bin/umount of `/mnt/usb' eject: unmount of `/mnt/usb' failed -------8<---------------->8----------- Some more information: -------8<---------------->8----------- # which eject /run/current-system/profile/bin/eject # mount /dev/sdb /mnt/usb # eject /mnt/usb eject: unable to exec /bin/umount of `/mnt/usb' eject: unmount of `/mnt/usb' failed -------8<---------------->8----------- HTH, let me know if you want me to test or provide anything else. Cheers, Alex
