Oberon/A2/myaos

#!/bin/bash # A script to start UnixAos or repository based A2 with a working # directory which can be in a removable flash store. # A flash store is accommodated in multiple machines by copying # machine specific configurations into Configuration.XML and # Oberon.Text. # # Conditions for this script to work. # * The volume containing the working files has a reliable name. # The names in /dev/disk/by-label/ and /dev/disk/by-uuid/ # are convenient. For example, a volume labeled A will appear # as /dev/disk/by-label/A. Additional details here. # https://wiki.archlinux.org/title/Persistent_block_device_naming # Udev in Wikipedia. # * Mounting of the working volume is specified in /etc/fstab. # What if the volume is automounted at a second location? # If edit conflict is avoided, a second mount is probably harmless. # * The following assignments to workingVolume and workingDirectory # are consistent with preceding information. # * An appropriate entry exists in /etc/fstab. Example. # /dev/A /home/me/A ext2 defaults,user,users,exec,noauto 0 0 # * /etc/sudoers.d/sudoers is adjusted to allow the user to fsck the # working filesystem. # me mycomputer = NOPASSWD: /sbin/fsck # Test fsck interactively. # * If the working volume is removeable the user can mount it. # Note the user option in /etc/fstab. # * Prior to revision.10272, aos attempts to create the link # <workingDirectory>/.aoshome to /usr/aos but the FAT file system # doesn't provide links.
